The effects of temperature and pressure on the wettability of metals by glass were studied. A system was completed that was capable of subjecting test combinations to temperatures up to 1400°C. at a working pressure of 10 −5 mm. of Hg. The variation in wetting with change in pressure and temperature was analyzed by the use of Young's equation primarily for the systems gold–, platinum–, and iron‐sodium silicate glass. The interfacial energy for the system gold‐sodium silicate glass was calculated to be 1230 dynes per cm. The limitations imposed on the use of Young's equation for analyzing wettability in systems in which an interfacial compound is formed are discussed.
