Abstract

25,736. Guinet, S. Nov. 22. Water colours; painting and varnishing.-Relates to the production of artificial or imitation marble by the application of a special paint on a foundation of glass or mirrors, wood, cardboard, stone, cement, plaster, &c. The paint consists of gold size, water, silicate of soda, and colouring- matter. Aniline or alizarine colours may be employed, or vegetable colours obtained by steeping wood sawdust, shavings, &c. in acetic acid, carbonizing the product by heat so as to produce the desired shade of colouring, and washing in the ordinary manner. When glass is used as a foundation, the painting is done on the back, and a coating of similar paint together with a mineral oxide or other earthy substance such as barium or calcium sulphate, lime, &c. is afterwards applied. The front surface may be slightly ground or treated with acid to reduce its brilliance. The panels &c. of imitation marble may be fixed in position by cement, heavy lime, or plaster, prior to which a varnish may be applied to the inner face. The invention is applicable to ornamental panels or slabs for decorative purposes, or the material may replace porcelain or earthenware for toilet furniture &c. Shields, escutcheons, mirror or photograph frames, tables, advertising-tablets, &c. may also be prepared in the same way.
