(© Carlo Mattogno 318 )It seems therefore that a blue pigmentation of masonry is no exception,but rather a rule, particularly where unprotected masonry isrepeatedly exposed to hydrogen cyanide over long periods. The largescale,long-term use of hydrogen cyanide for vermin control in disinfestationchambers only began, in practice, with the onset of the SecondWorld War. And with the dissolution of the National Socialistprisoner camps, the confiscation of the corporation having manufacturedand marketed Zyklon B (the I.G. Farbenindustrie AG), and theinvention of DDT at the end of World War II, this large-scale use ofhydrogen cyanide ended just as abruptly. No one cared about any ‘instancesof building damage’ having occurred in the former NationalSocialist disinfestation chambers in this period. The question neverarose in the literature… until Frederick A. Leuchter came along.The following is an attempt to demonstrate the manner in whichthese blue pigments, referred to as Iron Blue, came to be formed in themasonry during fumigation with HCN, and the conditions favorable totheir formation.There have been many publications on this chemical compound inthe last five decades, which were perused and will be summarized inthe following in relation to our topic. In so doing, attention was directedat:1) the circumstances which lead to the formation of Iron Blue, and2) the long-term stability of Iron Blue under the existing circumstances.318 Taken from the book by Carlo Mattogno, Jürgen Graf, Das KL Stutthof, op. cit.
