This work is an application of the so‐called mineral analysis to bodies fired to a maximum temperature corresponding to cone 9, for the purpose of establishing a measure of the progressive vitrification. It is based on the assumption that the solubility of an earthenware body in hot sulphuric acid decreases with the temperature of firing, as the porosity decreases. In general, this was found to be true but in order to obtain consistent results it is necessary to maintain standardized conditions of procedure especially in the grinding of the sample and in the treatment with fuming acid. The procedure has shown solution of as much as 66 % of the anhydrous clay substance with a porosity of 17.9%.
