The heat capacity of hydrous multicomponent natural melts and glasses

The model reproduces values of Cpliquid to within an average relative error of ~ 2.4%. Published models for the heat capacities of silicate melts (e.g., Stebbins, 1984; Richet and Bottinga, 1985; Lange and Navrotsky, 1992) applied to the same dataset have average relative errors in excess of 5.5%.
