FROM MAYCO:

Mayco’s Fundamentals® Underglazes are formulated for application to greenware or bisque, can be fired from cone 06 to cone 10, producing vibrant colors. Like all Mayco products, our colors are produced under strict manufacturing conditions and are quality controlled for consistent and dependable performance. Fundamentals® will fire to a soft, matte finish when left unglazed. Applying a clear glaze will create a brilliant gloss finish to your surface.

General Use

Shake well. Apply to wet clay, greenware, or cone 04 bisque for use in design or solid coverage. Fundamentals® Underglazes have a firing range from cone 06 to cone 10. To intensify color or for use on dinnerware, apply clear or matte clear glaze. For use on clay or greenware, apply underglaze, allow to dry and fire to cone 04. If desired, apply clear glaze and refire to cone 06-05 for earthenware and cone 5-10 for stoneware (998°C–1285°C). For use on bisque, apply to cone 04 bisque, apply clear glaze if desired and refire earthenware to cone 06/05 and cone 5-10 for stoneware.

Fundamentals® Underglazes have been formulated to mature at low-fire temperatures; however most will maintain their color at higher temperatures. Their performance at cone 6 is noted on each individual product label. Results at cone 6 may also be found at the end of the brochure. We recommend testing on your clay body and in your kiln prior to use.

Fundamentals® Underglazes are AP Certified Non-Toxic and dinnerware safe when clear glaze is applied.
