    of copper. After standing for a few weeks the pigment is separated from the unoxidized copper by washing through a sieve. It is then to be well washed, and dried slowly in the shade. It is often reduced with white lead; some samples contain arsenic. Arsenical Copper Greens. Of these there are several varieties. Mineral Green, Scheele’s Green, or Arsenite of Copper. 1. Dissolve 11 oz. of white arsenic and 2 lb of carbonate of potash, by heat, in a gallon of water. Dissolve also 2 lb of sulphate of copper in 3 gallons of water. Filter each solution separately, and add the former gradually to the latter as long as it occasions a precipitate. Wash the pre- cipitate, drain it, and dry it. 2. Dissolve 50 lb of sulphate of copper and 10 lb of lime in 20 gallons of good vinegar, and add quickly a boiling hot solution of 50 lb of white arsenic. Stir repeatedly, then allow it to settle; decant the clear liquor (which is reserved to dissolve the arsenic next time), and wash the precipitate, and dry it. 3. Emerald Green. Mix 10 parts of pure verdigris with sufficient boiling water to form a soft pulp, and strain this through a sieve. Dissolve 9 or 10 parts of white arsenic in 100 parts of boiling water, and, whilst boiling, let the verdigris pulp be gradually added, constantly stirring the mixture till the precipitate becomes a heavy, granular powder. Green without Arsenic. Dissolve 48 lb of sulphate of copper, and 2 lb of bichromate of potash in water, and add to the clear solution 2 lb of pearlash and 1 lb of chalk. JRinmann’s Green Pigment. Dissolve together in sufficient water 1 part of sulphate of cobalt and 3 of sulphate of zinc ; precipitate with carbonate of soda, wash the precipitate, and calcine it. Chrome Green. A mixture of chrome yellow and Prussian blue. [See also Chrome Oxide, p. 331.] Barth’s Green, A mixture of Prussian blue and yellow lake. Ultramarine, Factitious. Take 70 parts of silica, or pure siliceous sand, in fine powder; 240 parts of recrys- tallized alum, calcined; 144 parts of sulphur; 48 parts of
