A bstract Experiments, which included the development of methods of measuring the linear rates of crystal growth and crystal solution and a study of surface crystallization, were conducted on commercial‐type glasses. A method of studying interdiffusion of two glasses of similar composition is described but no conclusions were reached. It was found that ( a ) the rate of crystal growth is constant until the crystallization zones from the opposite surfaces meet and ( b ) the curve of crystal solution is continuous with that of crystal growth as the temperature is raised above the liquidus temperature. The results indicate that dust in the atmosphere is a major contributing factor promoting surface devitrification.
