Qualitative X‐ray diffraction of a fireclay brick revealed no major change in crystalline composition, other than the inversion of cristobalite, from room temperature to 1500°C. Methods of quantitative analysis of specimens at room temperature were considered. The internal standard technique of quantitative X‐ray diffraction was selected as the most reliable. Using this technique the effectiveness of quenching was investigated. Quenched analyses appear to be suitable for representing the constitution at high temperatures.
