Workshop receipts
Workshop receipts is a practical handbook of trade recipes and technical processes, compiled by Ernest Spon, Robert Haldane and Charles G. Warnford Lock and published in London and New York in 1883 for tradesmen and workshop practitioners. Its pictures are plain line diagrams of apparatus: a mounted wheel on a board, a fitting with a clamp, a sectioned furnace with a crucible and a tapered mould, and a brick kiln with pots and a flue. A designer might draw on their clean, schematic linework and labelled cutaway views for technical or industrial graphics.
