Refractory Cordierite Kiln Post For Firing , Good Thermal Shock Resistance
1. Product Details
Cordierite Kiln post is made of Magnesium Aluminum Silicate which has very low thermal expansion and low thermal conductivity. Cordierite can withstand fast heating or cooling and is used when thermal shock is a concern traditionally used in top loading electric kilns. Cordierite kiln shelves are more susceptible to warping at higher temperatures with maximum firing temperature is cone 8. Shelves used up to cone 6 should be at least ¾” thick, and those used to a maximum of cone 10 should be at least 1” thick which makes them heavy. Cordierite has 13-25% porosity rate which will be a problem with glaze dripping (the glaze can easily penetrate the surface and melt into the shelf). Kiln wash should therefore be used to protect the surface. Cordierite kiln shelves are not recommended for salt or wood firings.
