— Incorporation of the MELTS silicate melt solution model into models of evaporation successfully reproduces the evaporation behavior of alkali‐free, FeO‐bearing (≥2 mol%) chondritic melts at temperatures between 1700 and 2000 °C. In conjunction with the Berman CMAS melt solution model for FeO‐poor melts, evaporation of alkali‐free melts can now be modeled over a very wide range of conditions. MELTS‐based evaporation models can also quite successfully reproduce the evaporation behavior of K when Al/(Na + K) > 1. However, reproduction of Na evaporation experiments is much poorer.
