A bstract The rate of homogenizing of soda‐lime‐silica glass under conditions of minimum convection mixing and in the absence of refractory materials was measured by the centrifuge density spread technique developed by Turnbull and Ghering. Measurements on melts prepared in pure platinum containers at 2550°F. showed that the density spread decreases rapidly during the first 16 hours of melting following which further decrease occurs at a much slower rate. The portion of glass responsible for the major part of the density spread was a light fraction, which tended to form or accumulate at the surface of the melt.
