Definitions
- Substantial quantities of heat are required for the melting process, generally supplied by combustion of fossil fuels.
- the heat supplied to the melt is provided predominantly by natural gas mixed with preheated combustion air or natural gas mixed with oxygen.
- the resultant flame fires over the melt and heat transfer to the melt is by radiation from the flame and the furnace enclosure, and by convection currents.
- the melting of the scrap fibrous glass 62 causes the encapsulation of the glass batch material, thereby preventing the borates in the glass batch material 16 from pooling and attacking the glass line refractory. It will also help reduce airborne particulate borate compounds normally formed during the loss of water by the borate materials. Also, by distributing the scrap fibrous glass 62 uniformly, rather than non- uniformly, the glass batch material 16 will melt more quickly.
- the term "generally uniform layer” means a layer of about one-half inch (1.27 centimeters) to about 3 inches (7.62 centimeters) thick.

Abstract
L'invention concerne un procédé de fusion du verre consistant à introduire un mélange vitrifiable (16) dans un four (10) de fusion de verre contenant du verre en fusion (12), et à déposer le mélange vitrifiable dans une zone (38) de dépôt de mélange vitrifiable située au-dessus du verre en fusion contenu dans le four. Des déchets de verre fibreux (62) contenant des enduits organiques sont déposés au-dessus du mélange vitrifiable dans la zone de dépôt de mélange vitrifiable. Les déchets de verre fibreux sont mélangés et les enduits organiques se volatilisent. Le mélange vitrifiable est alors fondu.
