Journal
The Journal of the Society of Glass Technology, published from 1917 in Sheffield for glassmakers, furnace engineers, and industrial chemists working on melting, forming, and testing glass. Illustrations are patent-style line drawings: sectional views of furnaces, gob feeders, and blowing machines, with dense diagonal hatching for cut metal and brick, stippled or ruled molten glass, and small numbered part keys throughout, usable as ready-made mechanical diagram texture.
