The quartz content is determined by making a rapid fusion of the feldspar without dissolving an appreciable amount of the quartz, crushing the fused mass, immersing a portion of it in a liquid of the proper index of refraction and comparing the visible quartz with standard samples containing known quantities of quartz. A difference of 5 per cent in quartz content can readily be detected. The fusion and optical examination can be made in two hours and does not require a knowledge of microscopy.
