Spectrum Underglazes are all lead-free, A/P non-toxic, and dinnerware safe when covered with a food safe clear glaze. Spectrum Underglazes can be used at almost any temperature range and can be applied to bisque or greenware. Two to three coats are required to achieve opaque vibrant colors. The samples shown are fired to cone 05 but can be fired to low temperature (cone 06/04) to high temperature (cone 9/10). Some color variation will occur at higher temperatures due to different clear coats, thicknesses can also affect the hue of each underglaze.
