1. A process for producing glass by charging to a melting furnace and melting therein a mixture of particulate glass batch and scrap glass fiber, including the steps of:

  • heating durable particulate heat transfer media which is larger in particle size than the glass bath with exhaust gases from the melting furnace;

    milling the scrap glass fibers in the presence of particulate glass batch to reduce the size of the scrap glass fibers to a usable size, the glass batch containing the scrap glass until it is milled;

    introducing the mixture into the other end of the container;

    rotating the container, during rotation the mixture and media tumbling and moving over each other in heat transfer relationship for a period of time sufficient to remove any organics from the scrap glass fibers; and

    moving the mixture in one direction through the rotating container for discharge and moving the media in the opposite direction for discharge at the other end.
