The renewed popularity of chrome-tin pink glazes, the increased demand to develop and improve these colors in a variety of glazes, namely kadless compositions, are at the origin of this project. Chrome-tin pinks have been used almost exclusively in leaded glazes because of the difficulty of obtaining good kadless pinks free of defects. The sphene structure of the chrome-tin pigment is relatively unstable in many types of glassy environments and in most glazes, will break down and produce white spots of discoloration specially when fired in a long cycle. It was felt that if chrome-tin pinks cannot be used in kadless glazes then their potential market value would not be healthy enough to invest time and effort and allocate precious lab resources for a product of limited growth potential The regulations of OSHA and EPA would limit the use of leaded glazes in the future. It was then decided to try and develop kadless glaze compositions that would be suitable for the chrome-tin pink pigments.
