Schmelzung und Ausscheidung der Metalle aus ihren Erzen
Schmelzung und Ausscheidung der Metalle aus ihren Erzen is a 1784 German metallurgy treatise by Franz Ludwig von Cancrin, published by the Andreäische Buchhandlung for mining and smelting practitioners. Its engraved plates show furnace sections, masonry hearths and plan views drawn with fine hatching and numbered figures. A designer might take from them the dense stone-block texture and the precise technical line work typical of 18th-century engineering plates.
