Important Safety $ Storage Requirements for Advancer Shelves:

Slow and medium firing cycles are recommended for most ADVANCER® Shelves. We do not recommend exceeding 325ºF (163ºC) per hour from ambient temperature up to 1000ºF (538ºC). We do not recommend exceeding 325ºF (163ºC) per hour during cooling from 1000ºF (538ºC) to ambient temperature. Force cooling, propping the kiln lid open and pulling peeps is not recommended. Dense loads such as solid sculpture or thick tile may require slower ramp rates. Do not allow direct flame impingement, place shelves away from burner ports, fireboxes, stoking slots and bag walls. Opening ports on the kiln or failure to follow the recommended ramp and cooling rates can result in thermal shock failure (cracked or broken shelves) from rapid temperature changes.
