text: The process of preparing a red cadmium sulfide telluridc pigment by calcining cadmium sulfide with a cadmium compound capable of reacting under calcination conditions with free sulfur to the extent that not in excess of 0.25% by weight of free sulfur will remain in the total solids weight of the finished pigment and a source of tellurium, said cadmium sulfide being precipitated from a technical grade of sulfide selected from the group consisting of Na s and Bats and said source of tellurium being present in a particle size of from about 0.02 micron to about 7 microns, and wherein prior to calcination operations by-product mineralizers are removed by washing to the extent that from about 0.5 to about 1.0% of soluble mineralizer will remain in the total solid weight of the pigment product.
