PIGMENTS, are preparations in a solid form, chiefly employed by painters, for imitating particular colours, and imparting them to the surface of bodies.
Pigments are obtained from animal, vegetable, and mineral substances; the last, however, are the most durable.—In the progress of this work, we have pointed out various materials, that may with advantage be applied to the purposes of the painter, especially under the articles Colour-making, and Colouring-matter: it would, therefore, be superfluous to repeat, in this place, those multifarious articles which are described in their alphabetical order; as the reader will be furnished with a distinct and complete arrangement of such matters, at the conclusion of this Encyclopædia, in the General Index of Reference.
