This study was carried out on two samples of Kushta Sammul far (Calx of Arsenic trioxide), one prepared by classical method of calcination and the other one by muffle furnace in order to set the parameters for its standardization and to observe similarity or dissimilarity between the two samples if any, to offer a more refined alternate method of calcination. The parameters of standardization included tests for luster, fineness, floating, and curd and lemon tests substantiated with analytical methods which included determination of moisture content, pH value, particle size distribution; and Fourier Transform Infrared Spectroscopy (FTIR). The study revealed almost similar results in the two samples with slight difference in the physicochemical properties. The methods and the findings may be used as reference to prepare and standardize Kushta Sammul far.
