Develop a lead-free glaze with the visual appearance of a leaded glaze. The hypothesis that an index of refraction gradient with localized lower surface viscosity yields a visually higher quality glaze will be tested.
To get the localized characteristics within the glaze, the chemical composition must be locally tailored. A dual glazing process of two different compositions is proposed control the chemical composition within the glaze.
The EPA has made a continuous effort to limit the use of lead in various industrial products and processes. The main reluctance of the dinnerware industry to change to lead-free glazes is the importance of visual appearance in the product. The creation of a lead-free glaze with durability and optical qualities at least as good as that exhibited by leaded glazes would help end the use of leaded glazes in U.S. whitewares industry.
