<p>In accordance with the method of this invention, glass-forming materials are subjected to heat and agitation sufficient to form a molten glass having some undissolved glass-forming materials, cords, and incompleted chemical reactions between the glass-forming materials and containing a high number of gaseous inclusions. This molten glass is subjected to a shearing action to complete the melting of any unmelted sand grains remaining from the glass-forming materials, and to complete the chemical reactions that may have been incomplete, and to remove any cords remaining but leave the glass with gaseous inclusions; this glass is thereafter subjected to centrifugal forces sufficient to remove the gaseous inclusions and thereby produce a refined molten glass having the desired homogeneity. In one embodiment of the invention, glass-forming materials are introduced into a first chamber wherein they are subjected to heat and agitation sufficient to form a molten glass having some undissolved glass-forming materials, cords, and incompleted chemical reactions between the glass-forming materials and containing a high number of gaseous inclusions. This glass is introduced into a second chamber, where it is subjected to a shearing action to remove remaining inhomogeneities and complete the melting of the glass; this molten, homogenized glass containing gaseous inclusions is introduced to a third chamber where it is subjected to centrifugal forces sufficient to remove the gaseous inclusions, producing a refined, homogeneous molten glass, which is discharged from the third chamber.</p> |
