AbstractStudy of the X-ray diffractograms of fired samples of a brick clay revealed that the ratio of the intensities of quartz reflection at 3.34 A to that of labradorite reflection at 3.2 A is a linear function of the temperature at which the samples have been fired. This relation can be used to estimate the firing temperature of a particular brick, with standard deviation of 7.75 degrees C. The method described can be valuable in assessing freeze-thaw resistance of brick and in detecting temperature gradients in kilns.
