In this article (PDF-download), the gas chamber temperature is determined with Zyklon B mass gassings based judicially known witnesses and forensic investigations of Zyklon B in conjunction with other, well-known material data according to size by scientific methods approximate.
In the context of mass destruction by means of gas chambers as part of the Holocaust, the gas chamber temperature has not yet been sufficiently explored in Zyklon B mass gassings in the past, neither of revisionist side nor from the anti-revisionist side. The gas chambers in which using the agent Zyklon B insecticide million Jews were gassed, symbolize the Holocaust than any other feature. Therefore, it is necessary to examine what is happening in these gas chambers as accurately as possible.
Unfortunately, the gas chamber operating temperatures are handed down regarding any specific records or test results. However, there are numerous traditions about the killing times in the gas chambers of various post-war court case, such as of Rudolf Hoess in the Nuremberg trials. For these testified only a few minutes long kill times, the operating temperatures of the gas chambers are reconstructed by applying scientific methods approximate.
Generally, the release rate of the hydrogen cyanide from the insecticide Zyklon B is dependent on the ambient temperature. To determine the gas chamber temperatures each testified lying only in the range of minutes killing time is used. Depending on the testimony result from the gas chamber temperatures of 1000 ° C to about 20000 ° C.
The following considerations apply to the two gas chambers in Auschwitz Birkenau, which are attested in the crematoria II + III. Since the gas chambers are destroyed and not even sure if the destroyed structures actually correspond to the state of the previous gas chambers and whether the known ruins at all represent the gas chambers, must for the purpose of further evaluation almost exclusively recognized by the history and the Holocaust Research testimonies be used.
Main conditions to determine the gas chamber temperatures
From the Holocaust research is known well attested and recognized as common knowledge:
- The physical properties of Zyklon B (bulk density, hydrocyanic acid, diatomaceous earth carrier medium, thermal conductivity, specific heat)
- The technical means by which the Zyklon B was introduced into the gas chamber (wire mesh columns, “Partie Mobile”, wire mesh insertion device) 
- The approximate amounts Zyklon B, which are used for gasification (ranging from about 1, or even from 4 to 10 kg)
- The approximate coverage density of the gas chamber (4-30 persons per square meter)
- The time at which the door was opened again (<10 to 30 minutes)
- The killing times (presently up to 20 minutes by a majority well attested focal point in 2-3 minutes)
Of these 6 points going into the study of the gas chamber temperature only the physical properties of Zyklon B and the design dimensions of the part “Partie Mobile” and the killing of time (points 1, 2, 6).
The other points are of interest only to the definition of the constraints. This includes in particular the door opening times as a control parameter.
Dead can not be killed. This seems to be superficially banal, but is important in this context. This means namely that the release of toxic gas must have been completed no later than the time of death. The release of toxic gas may have been indeed completed before the time of death. But any release of toxic gas after the death would have been not only futile but would also have the Verfahern delayed unnecessarily. One would have actually tried to make dead yet more dead, than they were there anyway.
If poison gas is released, the poison gas effect is not extinguished upon termination of the release of toxic gas. The poison gas effect is only off when no poison gas in the air is gone. It follows that must have been free from poison gas to the door opening time of the room.
From the first condition gives the essential requirement that the gas chamber temperature must have been so high that the time of sacrifice, all cyanide must have been vaporized at the latest. More precisely: the container surface temperature must have been so high that the existing in the container hydrocyanic acid to evaporate within the time of sacrifice. In a container, liquid can be converted to gas only by evaporation, but not significantly by evaporation.
This also means that even in a fictional extra heating of the Zyklon B container (“Partie Mobile”) this film temperature must be reached. So it does not matter whether the container has been heated by the gas temperature chamber or by a separate energy source. In both cases, the surface temperature of the container must be identical. In the case where the canister is done by heating the gas chamber temperature, as has been testified of course, the gas chamber temperature must have been greater than the corresponding surface temperature of the container. How much bigger can only be estimated approximately.
Identifying the necessary container surface temperature / gas chamber temperature
First, a summary graph which illustrate the correlations. Shown is a portion of the cross section through the Zyklon B containers “Partie Mobile”. The viewing limit is the green outer container sheet dar. links which are shown the ratios of the environment, particularly the red temperature profile in sheet metal container nearby. It can be seen thereby that initially the air temperature is substantially constant and sharply decreases in vicinity sheet. Between ambient air and the plate surface so there is a temperature difference.
This temperature difference is decisive for the magnitude of the external heat transfer.
Then you see a small drop in temperature within the green sheet. This is caused due to the thermal resistance of the sheet. The greater the flow of heat is, the greater is this temperature drop. Then you can see a steep drop in temperature during the transfer of energy through the already cyanide “dried” diatomaceous earth granules. Then, the region where the hydrogen cyanide is still contained in diatomaceous earth granules in liquid form and it can be seen that the temperature is constant in this area is.
This is because, as the hydrogen cyanide in the liquid state can not be heated above their boiling point. All energy that is supplied to the hydrogen cyanide in the liquid state at the boiling point, only the conversion of the hydrogen cyanide in liquid or vapor in the gas is used. The required heat of vaporization is about 44% of the water at the boiling point of water.
It can be seen that in the end two large temperature differences may occur: an outer and an inner temperature difference.
Initially, only the inner portion of container sheet is considered to liquid front. We’ll look at the heat energy, which had to be expended up to the point where just the last cyanide is just evaporated.
Using the spent heat energy which has passed through the layers in a given time, considering the heat resistance required for this purpose, the surface temperature of the container can be determined.
The individual supplied heat energy were then, based on 1 kg of Zyklon B and the temperature difference of 1 K between plate temperature and the boiling point of hydrogen cyanide:
Temperaturverlauf = temperature profile
Gaskammer = gas chamber
Behälterblech = container sheet
Trockenes Granulat = Dry granules
Nasses Granulat = Wet granules
Zyklon B Behälter = Zyklon B container
Innen = inside
Heating of the iron sheet on the then prevailing sheet temperature
Q1 = s * cp * rho * F
s = sheet thickness estimated 0.0005 m (0.5 mm)
cp = 449 J/kgK
rho = 7874 kg/m³
The surface F results from the Zyklon B bulk volume and bulk floor area of the part “Partie Mobile”. The bulk volume is 0.00361 m³ / kg. The bulk ground floor space (0.15 m) ^ 2 – (0.1 m) ^ 2 = 0.0125 m². This results in a filling height of 0.00361 m³ / kg / 0.0125 m = 0.2888 m / kg. The heat transfer surface area of the square container is then for 1 kg of Zyklon B (1 kg hydrogen cyanide)
F = 4 * 0.15 m * 0.2888 m/kg = 0.1733 m²/kg
Q1 = 0.0005 m * 449 J/kgK * 7874 kg/m³ * 0.1733 m/kg = 306.34 J/kgK
Heating of the dry granules
to half the internal temperature difference between the plate temperature and hydrocyanic acid boil temperature . The hydrocyanic acid is absorbed in Zyklon B in 1.22 kg dry diatomaceous earth granules. Diatomaceous earth having a specific heat of 879 J/kgK. Accordingly, a quantity of heat has to be supplied from (based on metal temperature):
Q2 = 1/2 * 1.22 * 879 J/kgK = 536.18 J/kgK
The heat of vaporization of the hydrogen cyanide
amounts to 996 J/g Therefore is
Q3 = 996 000 J/kg
Heating the resulting hydrogen cyanide vapor
on a not precisely known temperature, which will be somewhere between sheet temperature and Hydrocyanic acid boil temperature. For this purpose, it is proposed as a realistic calculation value is 1/5 of this temperature difference. This would mean that the hydrocyanic acid gas having a temperature Tsiede + 1/5 * (Tblech – Tsiede) flows from the container. However, since this value is uncertain, instead of the fifth and 0 is assumed. This value can therefore be neglected if you want to specify a minimum plate temperature.
Q4 = 1/5 * cp
cp = 2000 J/kgK
Q4 = 400 J/kgK
This results in a all of the supplied heat quantity
Q at a temperature difference between the plate temperature and Hydrocyanic acid boil temperature of dT for 1 kg of Zyklon B
Q = dT * (Q1 + Q2 + Q4) + Q3
Q = dT * (306.34 J/kgK + 536.18 J/kgK + 400 J/kgK) + 996 000 J/kg
or summarized for 1 kg of Zyklon B:
Q = dT * 1242 J/kgK + 996 000 J/kg
The average specific heat output during the evaporation time is then
N [W/kg] = Q / evaporation time [s]
and the mean specific heat output is related to the surface
N [W/m²] = Q / (vaporization time [s] * F)
How big dT must now be actually so that cyanide can be vaporized, can not be specified directly. But you can set up a formula from which will indicate what
Time required for the gasification
is needed to vaporize the hydrogen cyanide for a given temperature difference dT between the sheet metal and cyanide. For this purpose, the thermal conductivity of the dried diatomaceous earth granules is only needed. This is itself dependent on the temperature and is
lambda = (0.08 + 0.00015 T/°C) W/mK
Since the dried granulate is located in the middle at half the temperature difference = 26 °C + dT/2 is then taken for T and effective.
Then, the formula, with the Zyklon granules layer thickness d according to the design data of the part “game Mobile” 25mm, that is 0.025 m:
Time = heat per area / temperature difference * Heat Resistance / 2
Time = (Q / F) / (2 * lambda / d * dT)
Time = ((dT * 1242 J/kgK + 996 000 J/kg) / 0.1733 m²/ kg) / (2 * (0.08 + 0.00015 * (26 ° C + dT / 2)) J/smK / 0.025 m * dT)
or as pure numerical value equation:
Time [s] = ((dT * 1242 +996000) / 0.1733) / (2 * (0.08 +0.00015 * (26 + dT/2)) / 0.025 * dT)
and further summarized:
Time [s] = (7187 + 5747000 / dT) / (6.4 +0.012 * (26 + dT/2))
Time [min] = (7187+5747000 / dT) / (384 + 0.72 * (26 + dT/2))
This results in the following surface temperatures, these evaporation times, all of which are within the witnessed killing time range:
860 °C: 1200s = 20 minutes
1500 °C: 711s = 12 minutes
3000 °C: 371s = 6.2 minutes
6000 °C: 191S = 3.2 minutes
9000 °C: 129S = 2.1 minutes
20000 °C: 59s = 1 minute
For comparison, some low surface temperatures:
150 °C: 120 minutes, ie two hours evaporation time.
281 °C: 60 minutes, so 1 hours evaporation time.
The calculated evaporation times correspond to at least the kill times.
(Optimum amount of Zyklon B and required gas chamber temperature
for the gasification of 1,800 Jews depending on the killing time in crematorium 2 Birkennau at 1 mgHCN / kg lethal dose. To the time of death, the entire amount of hydrogen cyanide is evaporated.)
(Minuten Tötungszeit = Minutes killing time)
(Optimum amount of Zyklon B and required gas chamber temperature
for the gasification of 1800 Jews depending on the killing time in crematorium 2 Birkennau at 1 mgHCN/kg lethal dose. To the time of death, the entire amount of hydrogen cyanide is evaporated.)
(Minuten Tötungszeit = Minutes killing time)
Apart from the purely mathematical determination of the gas chamber temperatures, there is also the possibility of its simple experimental verification, which can be practiced by anyone in a matter of minutes with a budget and a thermometer. While this verification option is not exact, however, proves the approximate accuracy of the above gas chamber temperatures. Thus, ultimately, the possibility of gasification is even proved experimentally. In the commemorative publication “The mug of beer and the Holocaust”  the experiment and its evaluation is presented in an easy to understand.
From the physical methodology resulting conclusions
In this analysis, the Zyklon quantities, the toxicity of cyanide, victim numbers played during gasification, gas chamber size, number of roof openings and feasibility no role, as was expected only with specific values (reference 1 kg Zyklon B). The gas chamber temperatures were, of course, especially at the low temperatures still much higher than the calculated sheet surface temperatures. We can therefore say that the Jews were gassed always above 1000 °C gas chamber temperature, since the longest time of sacrifice was witnessed by 20 minutes only in exceptional cases (perhaps during the high heating or during cooling of the gas chamber).
According to testimony from camp physician Dr. Horst Fischer , which oversaw the mass gassings, the occurrence of death usually occurred within 2 to 3 minutes. According to the above physical methodology this results in gas chamber operating temperatures of 6000 °C to 9000 °C. Although these temperatures can be doubted by several hundred degrees up or down, but the basic temperature level can not be refuted.
It must therefore be assumed that the Jews after the killing with the help of the undisputed highly toxic cyanide “usual” at the 9000 °C gas chamber temperature have been transferred within a few seconds after her death in the gaseous state, were so gassed sense of the word after. With Document 3311-PS of the Polish government provides the winning tribunal on that in Treblinka “evaporates” hundreds of thousands of Jews were. The VS-lead plaintiff, Robert Jackson, accused the Germans of having a ‘newly invented device’ is used, with the near Auschwitz on the spot 20000 Jews were ‘vaporized’ in a way that left no traces. Due to the usual testified occupancy densities of around 7-8 Jews per square meter (equivalent to 1500 Jews for the 210m ² large gas chamber) lie in the basis of 4 Apertures a 0.5 m² amazingly high gas chamber pressures. After all, were then within, for example, 13 seconds generates 90 tons of Jews gas that could escape simultaneously through the Zyklon-B insertion openings at this time. This happened at a constant gas chamber pressure of about 60 bar and multiple speed of sound.
Due to the mixing of the gas mass thus produced volume (90000 kg) with the relatively low prussic acid quantity (eg 6 kg) was the gas chamber to be filled after these 13 seconds with new victims, as the cyanide concentration was diluted in the meantime to dangerous low levels. In addition, one minute, the gas chamber was at these high temperatures alone by the strong convection cooling through the mail slot even without special ventilation devices in probably adequately ventilated.
It is understood that a technology was necessary for these amazing benefits, which is completely unknown and unimaginable nowadays. There are no materials which are solid or liquid even at 6000 °C. Any material can exist at such temperatures at ambient pressure only in the gaseous state.
Only the testimony of the postwar trial of the only few minutes long kill times give us the evidence or prove even clear that at that time the offender must have dominated such incredible technologies during the Nazi era. Six million Jews testify to this.
Virtual reconstruction of the gas chamber with wire mesh columns
Miklos Nyiszli and David Olère: As part of the educational project of a Brazilian history teacher, a film with virtual reconstruction equipped with wire mesh columns gas chambers on the basis of sources Pressac (“Technique and Operation of the Gas Chambers of Auschwitz”) was born. The wire mesh columns are to see at the position between 0:30 to 1:00 min in the movie.
The importance of the wire-mesh columns for the Holocaust is emphasized here
Holocaust-deniers reject that these columns even existed. The convergence of this evidence, including the compelling testimonies giving details before corroborating documentary evidence was unearthed, is ignored.
Kula’s and Tauber’s depositions describing the “wire-mesh insertion devices,” decades before the corroborating documentary evidence was discovered in the archives, cannot be explained away. Houstek/Erber’s description of the same devices, also before that evidence was discovered, is also a powerful corroboration.
Deniers will likely argue that the minor differences in their descriptions mean we should ignore them. But should we really expect to find identical accounts? The prisoners gave their descriptions months after the fact; the perpetrator, 35 years later. That may account for some of the difference. Just as importantly, we do not know if the Nazis in charge of the gassing operation tried slightly different types of equipment from time to time.
Indeed, if all three descriptions were exactly alike, we might suspect that the later account was copied from the earlier ones. Because they are not, we know that here are three separateeyewitnesses to these items.
Holocaust-deniers reject the validity of the aerial photographs, claiming that the four dark spots on the roof of each gas chamber were retouchings added by the CIA or some other conspiracy. John Ball, who has no expertise in interpreting aerial photographs, suggests either that hypothesis or, alternatively, that the dark spots were flowerpots sitting on each gas chamber.
The objects shown on the roof in the ground photo, say some deniers, are ordinary boxes of construction material.
Deniers also claim that there is no evidence of four holes in the roof of each gas chamber. Because the chambers were dynamited in an attempt to hide evidence of mass murder from the approaching Soviet army, the roofs have collapsed and it is difficult to tell in the rubble what is a hole and what is not. Later this year, an essay on this website will address this question in detail.
Finally, Holocaust-deniers intentionally confuse the solid support columns for the gas chamber roof with the wire-mesh columns. As obvious evidence of their crimes, the latter would have been removed by the Nazis from the gas chambers before they were blown up. Ludicrously, deniers show photos of the solid columns as proof that the wire-mesh columns never existed.
Such feeble attempts to rewrite history do not stand. 
From the van Pelt reports, citations to the wire mesh columns:
“The pages of this column, who went through the roof, were of heavy wire mesh. Within this network, there was an even finer mesh and in a third, very fine mesh. In this last case there was a removable mesh liner, which was pulled from a wire to get the [Zyklon] pellets from which the gas had evaporated.”
“The ceiling of the gas chamber was supported by concrete pillars, which were arranged in the center of the room lengthwise. Four more, two were on each side on the sides of these pillars. The sides of these columns, which ranged through through the roof, were of heavy wire mesh. In this network, there was another finer mesh and in a third, very fine wire mesh. In this last wire cage there was a removable sleeve to get the pellets from which the gas had evaporated.”
“Tauber’s testimony is undoubtedly the most important document on the destruction process, which was created immediately after the war. It is essentially confirmed by contemporary statements Jankowski and Dragons, and by the later drawn up memories of Filip Müller.”
“It is very unlikely that Filip Müller’s memories of Tauber’s testimony were inspired or influenced.”
“Among other things, shower dummies were in the locksmith produced, which are then installed in the gas chambers as well as lattice pillars through which you einschüttete the content of the Zyklon rifles in the gas chambers. These pillars were about three feet high. Their diameter was perhaps 70 cm. Such pillars consisted of three superimposed clips wire nets. The outer wire net was made of 3 mm thick wire; the cornerstone extent 50 x 10 mm. Such cornerstone rejected the wire column top, bottom as the link to the pages. The meshes of the outer wire mesh having a diameter of about 45 mm. The second wire network was constructed the same as the outer and about 150 mm of that away. The diameter of its mesh maybe was 25 mm. At the corners of these two gratings were associated with iron wires. The third component of the pillar was movable. These were an empty mesh of thin zinc plate diameter of about 150 mm, which resulted in a hopper above and below had a square area.”
“There are also German documents that substantiate the fact that the gas chamber was heated (a fact which, as I have stated above, strongly indicate that this room was not designed as morgues).”
Yisrael Gutman and Michael Berenbaum
Yisrael Gutman and Michael Berenbaum describe the operation and appearance of the wire-mesh columns in the crematoria II and III of the Auschwitz concentration camp in her book Anatomy of the Auschwitz death camp as follows: 
“Zyklon B was distributed in the gas chamber by four custom-made in the fitting of the bearing induction columns. They consisted of two wire grids with a movable core and shaped like columns. Cross sections of 3m tall pillars formed a square whose side measure 70cm. At the bottom mounted, they went through openings in the ceiling and ended outside as small chimneys, which were covered with a concrete lid with two handles. The external network (consisting of 3 mm thick wire) made of 45 mm x 45 mm measuring gaps and was involved in cubic metal posts attached (cross section 50 mm x 10 mm). The interstices of the outer network – 150 mm from the inner network and secured similar – were smaller (25 mm x 25 mm). The two networks served as a protection for the movable core, which could be inserted through the cover into the opening. The core consisted of a 150 mm x 150 mm in cross-section measuring Zinnprisma. The underside of the core was flat, and the top a cone. A wire mesh at intervals of one square millimeter was from the base of the core to the base of the cone and attached to a 25 mm distant pole. The entire length of the core was covered with tin. If Zyklon B pellets fell on the cone, it was evenly distributed in the nucleus and was stopped at its lower part. After the gas had evaporated, the entire core was removed from the gas chamber and the used diatomaceous earth granules is spilled.”
Further, resulting from physical considerations methodology
Failed holocausts of the Jews are already attested in the Bible by the Jews themselves. So it says that Nebuchadnezzar had been present unsuccessfully to burn three Jews in a sevenfold hotter oven. At Daniel 3,1.4-6.8.12-26 is to read that this attempt ultimately failed. 
In connection but with the modern Holocaust can be seen that were, according to all reports nowadays referred to in the official media to the 6 million Jews killed with Zyklon B and, due to the underlying technical conditions described, then gassed within seconds. In this respect, the word “Holocaust” is not entirely correct, because the Jews were not burned in these gassings. They were literally “only” gassed. This took place generally at temperatures of 6000 °C to 9000 °C, as can be uniquely reconstructed from the witness statements. Accordingly, it would be understandable that the Jews could never tell the public truthfully this truth. The credibility might have suffered, as it is nowadays accepted that there was no material at 6000 °C at normal pressure can be solid or liquid and yet that any material exist under these circumstances only as a gas. One would thus might refer to the Jews as liars.
Mindful of the difficulties in teaching the Holocaust to the world over, therefore, could be quite understand that the Jews were forced to add facts and rework documents in order to offer a holocaust so “natural” manner. Thus it turned out, however, forcibly, that they became entangled with their additional information and explanations more and this could therefore be detected by the revisionists.
Now, the Holocaust stands today, however, no doubt as an obvious fact because, and this is so contrary to the proven lies and fabrications of the Jews. Therefore, they must, in fact negating the Holocaust lies and fabrications are ultimately protected by the state by appropriate legislation. Taking the maximum temperature gas chambers after the set forth herein as an obvious fact, would therefore, as a necessary conclusion from this, to draw the amazing realization that the German Reich in 1945 the world was incalculable technologically far ahead.
However, this conclusion is only superficially correct, as it leaves the essential fact in mind, it would have been any human being possible to enter into such a high temperature-gas chambers. Every person would be killed before admission and evaporated by the radiation. It would have been him even when placed under allerbestem will be impossible to participate in a 2 minute gasification. Finally, it evaporates before admission with about 16 cm per second, if we assume only the minimum required gas chamber temperature of 9000 °C for this purpose. In the gas chamber temperature of about 100 000 degrees C, which is suggested by the also testified “instantaneous gassings” as the default operating temperature probably constantly used, the same rate of evaporation would have it no longer be already 70 m in front of the open gas chamber door itself at a run to reach the gas chamber door. Only Jewish victims this was possible, because only they have the necessary heat resistance.
It is also known that a man has in SS uniform cooking pots filled with the deadly Zyklon B granules lowered into the gas chamber. This man, too may never have been a German because he would have been vaporized from the gas chamber radiation within milliseconds. Also this man in an SS uniform must have necessarily has the necessary heat resistance, through which only Jews have.
This means that the Germans could not have carried out the Holocaust, but this was carried out for unknown reasons by the Jews themselves. Both as victims and as perpetrators. The Holocaust was obviously a purely internal Jewish matter of which the Germans had not even suspected something.  
Had the Germans had even a slightest knowledge of the Holocaust, they have also won the war. The calculation of the gas chamber pressure ratios in fact shows that the materials used were not only an extreme temperature resistance but who also have a tremendous strength which Krupp steel outperformed the best at that time to the more than 10000 times. With such material knowledge the Germans had won the war against any hostile power. This is also obvious that the ignorant Germans in the Holocaust had no debt. The culprit was the Germans pushed only into the shoes to distract from the true Jewish guilt.
The view expressed in this video at 7:15 apprehension of Professor Wolfgang Benz has also proved to be unfounded hereby:
“We should no longer speak of gasification … Or maybe there is a new client of yours, Mr. Attorney, and calls on the scientific evidence that the victims of Auschwitz have been transferred to these other aggregate state.”
The scientific evidence of the performed change of physical state of the Jews has been adduced!

“Zyklon B was distributed in the gas chamber through four introduction columns custom-made in the metalwork shops of the camp. They were shaped like pillars and made of two wire grids with a moveable core. Cross sections of the pillars, 3m high, formed a square, each side measuring 70cm. Fastened to the floor, they passed through openings in the ceiling, ending outside as little chimneys closed with a concrete cover equiped with two handles. The external grid (made of wire 3 mm thick) formed interstices measuring 45 mm x 45 mm, and was fastened to cube-shaped metal scantlings (cross section 50 mm x 10 mm). Interstices of the external grid–150 mm apart from the internal grid and similarly fastened–were smaller (25 mm x 25 mm). The two grids served as a screen for the moveable core that could be introduced through the opening in the ceiling. The core consisted of a tin prism measuring 150mm x 150 mm at the cross section. The bottom of the core was flat, and the top was a cone. A wire mesh with interstices of one sq mm extended from the base of the core to the base of the cone, and was fastened to a post 25 mm away. The entire length of the core was covered with tin. When Zyklon B pellets fell onto the cone, they spread uniformly throughout the core and stopped at its lower part. After the gas evaporated, the entire core was removed from the gas chamber and the used pellets of diatomite were poured out.”
