Liquidus data are reported for a series of forty-two ternary feldspar compositions, including compositions at each 10 per cent interval by weight of soda, potash, and lime feldspars. Only two fields, those of feldspar and leucite, appear on the liquidus surface. In addition to the liquidus data, the temperature of appearance of a second solid phase was determined for some of the compositions. Measurements of the index of refraction of the feldspar glasses are recorded. These data are principally of value as a starting point for studies of these same compositions with water as an additional component.
