A model was developed to predict the temperature distribution, heat transfer, and melting time during unsteady heating and conversion of batch to glass. Percolation of gas through the blanket of batch and heat absorption during the decomposition of carbonates are accounted for in the model. In the glassmelt, heat was assumed to be transferred by combined conduction and radiation. The model equations were solved numerically using a finite‐difference method. The effects of several model parameters were investigated. The results of computations show that percolation of gas through the batch increases the time required to convert the batch to glass. Absorption of heat and release of gas in the batch due to decomposition of carbonates changed the temperature distribution in the batchiglass system and the melting times were affected relatively little as long as the total energy absorbed during the transformation process remained unaltered.
