How do you use a pigment?

A paint consists of a pigment with a binder, usually a polymer, and may also contain a solvent or plasticiser to make the paint flow more easily. Early artists found egg yolk was a good binder: their paintings are still visible in the great art galleries, so they were right to choose it. Then natural drying oils were used such as linseed and the paints could be thinned by turpentine, obtained by distilling the resin from conifers. More recently trhe pigments were added to an emulsion of polymethyl methacrylate ( PMMA) or another acrylic polymer. the water evaporates to give a semi- permanent deposit, whereas the oil based paints react with the air to set solid. Restorers prefer the acrylic paints since they ar not as permanent as the oil based ones and also are not prone to yellowing. Dyes are soluble whereas pigments are usually not so.
