Abstract: Silica is reacted with sodium carbonate to form sodium silicate as a preliminary step in a glass melting process. Preferably, calcium carbonate-containing batch materials are calcined separately and then combined with the sodium silicate as liquefying is initiated. The materials may be substantially free of bubble-producing carbonates as the molten phase begins to form.

Abstract: Liquefying of pulverulent batch materials (e.g., glass batch) is carried out in two stages. The first stage utilizes extended gas/solid contact to heat the materials to an intermediate temperature, and may recover waste heat. The second stage rapidly liquefies the material in a cavity lined with the batch material, and may employ substantially nitrogen-free heat sources. Another aspect involves maintaining a wet condition in the first stage to entrap particulates.

Abstract: A method for producing decorated glass-ceramic articles is disclosed. The method involves contacting a surface of a crystallizable glass with molten tin and thereafter applying to the tin-contacting surface a stain decorating composition. The article is then fired at a temperature such that the glass simultaneously crystallizes and the stain diffuses into the article to form the decoration.

Abstract: Removal of gas inclusions from a molten glass pool is enhanced by inserting a gas inclusion-permeable, refractory metallic or ceramic screen in the downstream flowing, upper portion of the pool, to diminish the glass flow rate adjacent the surface by viscous drag forces while permitting gas inclusions to rise through the screen to the surface of the molten glass pool to dissipate into the atmosphere therealong.

Abstract: Raw materials such as glass batch are preheated by combustion of liquid or solid fuel such as fuel oil or coal mixed with the batch material. In one embodiment the material being heated and the gaseous products of combustion are passed cocurrently through the preheating stage to avoid carbonaceous effluents. Preheated materials and any ash from the fuel are transferred to a second stage where they are liquefied. Carbon monoxide from the preheating stage may serve as fuel for the liquefying stage.
