"The method of bloating brick of low refractoriness has been accomplished by the addition of carbonates of the alkalines and alkaline earths which when acid is applied give off CO₂ to form a porous structure. It was thought that if a material which would not act as a flux might even enhance the refractoriness of the clay used a high temperature insulator might be produced which would compare favorably to those now produced by the use of volatiles. An aluminum salt which when combines with a non-metalic sic base that would generate a gas was selected. The aluminum in the process of firing would oxidize to the refractory Al₂O₃ and the base would volatilize without detriment at the refractoriness of the brick"--Purpose, page 9.
