Very latest methods, special formulas and standard processes : secured in France, England, Belgium and Germany for the manufacture of varnishes
A varnish manufacturing manual compiled by Ernest Mas in 1889, likely printed in New York for the trade, gathering French, English, Belgian and German processes for making varnishes. Its pictures are plain line drawings of workshop equipment: a ventilating fan on a brick wall above a vat, a pair of tall tubs with workers tending them, and a long glass varnish thermometer. A designer might take from them a clean technical diagram style with simple hatched brickwork and mechanical detail.
