Descripción: Institute for Dynamic Educational Advancement (IDEA).
«Pigments are the basis of all paints, and have been used for millennia. They are ground colored material. Early pigments were simply as ground earth or clay, and were made into paint with spit or fat. Modern pigments are often sophisticated masterpieces of chemical engineering.»
