Very rare book about coluring of metals, coming from the former library of the Auschwtiz III Monowitz chemical complex, the famous IG Farben. That library was mainly based on chemistry, metalurgy, physics and other sciences' books, so that scientists working there could consult them. This libraty passed totally to Dwory Polish chemical complex since it closed down and some of the factories were abandoned, including this libraty. Book has stamps of Auschwitz III IG Farben Industrie and Dwory. Very rare since items from Monowitz are scarce!
