Take sized cloth then precip from a alkaline soln of wax the wax by means of an acid – and trowel on the wax hydrated paste when dry apply hot irons or perhaps dry friction – over which give a coat of flatting colour badgered – or perhaps mix a little grod white lead with the hydrated wax prepn or precipitate them together or try the wax prepn with a certain qy of sugar of lead used in the precipitating acid soln which throws down some carbonate lead in combination,To afford a smoother hydrated paste for troweling it should be precipitated from very dilute solution,
