Abstract

In the melting of glass, particularly of glasses which are of the low melting point variety in the range of 1,600* F., the melters conventionally used have been rather massive units. A metal-lined melter of lightweight construction is disclosed herein. The melter is compact, highly mobile, in the sense that it may be moved from one location to another location, and has great utility in the production of molten colorant additive for direct addition to a large capacity glass forehearth. The melter is constructed of one-eighth inch thick '"'"''"'"''"'"''"'"'Hastelloy X'"'"''"'"''"'"''"'"' alloy. A plurality of Kanthal heating elements are mounted in a ceramic muffle in substantially surrounding relationship with respect to the metal melter. An insulating, outer covering over this area is provided by two layers of firebrick. The entire unit is covered with a Transite material and totally supported by an angle iron frame s as to render the melting unit portable.

Claims

2. The melter of claim 1, wherein said overflow discharge means comprises a vertical tube extending through the bottom of the melter to a predetermined position below the top thereof.

3. The melter of claim 1, wherein said heating means comprises a plurality of electrical resistance elements positioned about said chamber and mounted within the notches in said muffle.
