Erythrosine

== Description ==
A brown powder that forms a cherry red synthetic dye solution with water. First discovered in 1876 by Kussamaul, erythrosine is an iodinate derivative of fluorescein. It is used as a direct dye on wool and silk. Erythrosine is also used in inks, lacquers, cosmetics, and as a lake pigment. It is not colorfast in sunlight.

Ester

== Description ==
A class of organic compounds that result from the reaction of an alcohol with an acid. An ester is the organic equivalent of an inorganic salt, and are even named as salts of organic acids. Most low molecular weight esters are solvents that are used in plastics and lacquers, such as ethyl acetate. Polymeric asters are called polyesters. Examples of ester polymers are polymethacrylate and polyethylene terephthalate. Many other synthetic esters have wide commercial uses, such as plasticizers (dibutyl phthalate) and soaps (triphenylphosphate).

Ester gum

== Description ==
A modified natural resin made from rosin that has been esterified by heating with a polyhydric alcohol, such as glycerol. Ester gum contains the glyceryl, methyl, and ethyl esters of rosin acids. Ester gums are lighter in color than rosin and have a higher softening point but lower acid number. They are used instead of copal, dammar, or kauri in making enamels, paints, nitrocellulose lacquers, and tung oil mixtures. Ester gums are not used in artist paints or varnishes although they have been tried for wax-resin linings.

Etching ground

== Description ==
A non-reactive, non-soluble material used for coating the surface of the material to be etched. The etching ground is usually heated then a thin layer is rolled or brushed onto the metal plate. A hard surface etching ground is made from mixing beeswax, asphalt and rosin.
