Abstract:
The nature of my invention consists in using:
1st, flowers of sulfur, sulfuric acid, and carbonate of lead in forming Prussian-blue. 2nd, in using nitric acid, and carbonate of lead to form chrome yellow. 3rd, in the further use of flowers of sulfur to form chrome green, 4th, in the formation of a metallic green from sulfate of copper, and carbonate of lead.
Claim:
The using of flowers of sulfur, sulfuric acid, and carbonate of lead in forming Prussian blue as the flowers of sulfur contains a slight degree of acid which is not easily extracted by coming in contact with an alkaline substance, I use it to support the blue I use sulfuric acid to assist in saturating the composition with oxygen which forms tile blue, I use the carbonate of lead to precipitate the iron, to discharge the superfluous acid, and to assist in forming a body to the paint. |
