Not every furnace is suitable for glass melting. Glasses often have corrosive compositions whose fumes and splatter can attack fiberboard furnace linings and heating elements. You don’t want a furnace whose interior resembles the face of the moon; you don’t want the protective coating on the molydisilicide heating elements literally running down the element and dripping onto the load platform.
Deltech glass melt furnaces will perform under the most rigorous of environmental and cycling conditions. They were originally designed for use in a national lab research setting in which the furnaces saw 24/7 use and many glass formulations. Today these furnaces are widely used in universities, government, and industrial settings for the R&D of bio, optical, nuclear waste containment, and other specialty glasses.
