Abstract
A method is taught for separately preheating cullet and batch, material use in glass making. This method uses a two stage process for preheating batch in a way that allows water vapor to escape to the atmosphere before the main preheating stage. It supplements current preheating methods of the art of glass making. Apparatuses to carry out this method are also taught.
