DIY Refractory Compositions [Archive] – AlloyAvenue network
At high temperatures, which depend on the compound in question, fluxes attack acids or glass formers, lower their melting point, and together form a glass. Soda lime glass, for instance, is easily melted in a furnace because of the large amounts of soda and lime, while pure silica is much harder to melt.
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.

How-To: Homemade Castable Refractories | Make:
Apr 05, 2012· Wikipedia quotes ASTM C71 on the definition of refractory: “non-metallic materials having those chemical and physical properties that make them applicable for structures, or as components of systems, that are exposed to environments above 1,000 °F.”They are commonly used, for instance, to line kilns and other high-temperature furnaces. Castable refractories can be mixed with water, formed …
