Verre et verrerie
Verre et verrerie, an 1894 Paris treatise on glass and glassmaking by Léon Appert and Jules Henrivaux, written for practising glassmakers and engineers. Its pictures are numbered line engravings of furnaces, a regenerative gas-fired melting furnace, moulds, and rail-mounted handling trolleys, drawn in precise cross-sections and elevations that a designer could use for industrial, mechanical, or technical diagram styling.
