Have managed to buy this weighty tome to-day. @ 350pages, on Czech glass, dating to 1947. Does anyone have a view as to its accuracy/reliability, given that Volf was a CP stooge, and Dr Ctyroky spent most of his life in internal exile? For me, Ctyroky, the leading glass technologist of his era, was badly treated by the Communists, and certainly was handed the shitty end of the stick.
Is this pre-communist era treatise on glass valuable for its information, or to be treated as a suspect device?
TIA,
Marcus
