coloured engraving of a laboratory used for chemical analysis or assaying. The various pieces of equipment are labelled by letters. ''A'' is a furnace used to melt samples. ''B'' is a tray into which these samples are poured. ''C'' is a mask used to protect the face of the person viewing them. ''D'' is a flask that,when heated,will separate out volatile elements from a substance. ''E'' is a water displacement apparatus (the density of the sample can be determined by measuring how much water is displaced by a given weight of sample). The illustration is taken from ''Beschreibung allerfurnemsten Mineralischen Erzt und Berckwercksarten'' (1574) by Lazarus Ercker | |
