What is fire clay and where to get it in nature
All refractory are based on fire clay what it contains alumina and silica. In fact all high heat resistant firebricks are made of fire clay. Like heat resistant mortars insulation pottery ceramics ceramic blankets or ceramic tiles on space shuttle origins of these start from the fire clay its melting starts at 1600 Celsius °C or 2912 Fahrenheit °F point. Slake it as described in 3 above. When it is all soft and mushy stir it until it is a slip. I use a mixer on an electric drill or a blunger. Add water if needed to liquefy it. Pour the slip through ordinary window screen available at any building supply store. The screening removes

Difference between refractory castable refractory cement
Many people can t tell the difference between refractory cement refractory castable and refractory mortar. Simply speaking refractory cement is used as binder of refractory castable sometimes it is used as a binder of refractory mortar and it is rarely used alone. 3. Economy. Since the quality depends mainly on the water to cement ratio the water requirement should be minimized to reduce the cement requirement (and thus reduce the cost). Take these steps to reduce the water and cement requirements use the stiffest mix possible use the largest size aggregate practical for the job.
