A method of removing coatings from scrap glass is disclosed. The scrap glass is milled in the presence of particulate batch, preheated and fed to a glass melting furnace. The particulate batch aids in the milling of the scrap glass. The process removes the coatings from the scrap during preheating and provides clean material for melting.
