The liquidus temperatures of a 19 wt% soda‐silica glass prepared by gel and conventional techniques were determined. X‐ray diffraction measurements of the glasses which were heat‐treated at several temperatures were used to experimentally determine the liquidus temperatures. It was found that the gel‐derived glass has an elevated liquidus. This result is discussed in relation to the previous discovery that the immiscibility temperature of this gel‐derived glass is elevated.
