This white, often employed for decorating and for artistic painting, is a white lead of the first quality which has been peculiarly well washed. ,A superior quality of silver white for delicate oil painting may be obtained by dissolving 500 grammes of acetate of lead in 2 litres of boiling water and diluting with 4 litres more of water. Then a solution of 370 grammes of soda crystals in 2 litres of boiling water, is slowly poured into the former liquors, stirring all the while. The two mixed solutions are allowed to settle for two hours, when the supernatant liquid is decanted. The precipitate is washed five or six times by decantation, then drained upon a cloth, and dried in the dark at a gentle heat.
