A study is made of the effect of heat at cone 13 and cone 14 on the index of refraction of the four common mineral forms of silica used in the ceramic industries. These mineral forms are sand, quartz, chalcedony and French flit. The effect of these mineral forms on the index of refraction of porcelain bodies fired to cone 13 and cone 14 is also given.
