Both are certifications received from the Art and Creative Materials Institute as a result of extensive toxicological testing. AP is for products that contain no materials in sufficient quantities to be toxic or injurious to humans, including children, or to cause acute or chronic health problems. CL is for products that are labeled in accordance with the chronic hazard labeling standard and are certified to be not hazardous if used in accordance with directions on packaging.
Speedball glazes and underglazes have a shelf life of 2 years after manufacture, however when properly stored and maintained they can last much longer.
To get the best results with Mid-Fire glazes, we recommend bisque firing to cone 05/04 and doing a test tile on your clay body and preferred firing method. We do not recommend any slow controlled cools, as this can effect the final appearance of the glaze.
Yes, however the finished appearance of many of the glazes may change at higher temperatures. We recommend doing test tiles and your own dinnerware safety testing prior to use on any finished pieces.

color overview
Cocoa Flux is a glossy glaze with a kiss of chocolate-colored undertones when used individually. An incredible glaze on its own, but it is meant for layering throughout the Mid-Fire glaze family (this tile is Cocoa Flux over Dragon's Eye). Cocoa Flux is highly effective with a standard 1-2 coats application to maximize eye-catching mottling. Formulated to cause fluxing or enhanced movement along ceramic surfaces, use caution when applying fluxes from midway to the bottom of outer ceramic vessels.
