METHOD OF MAKING GLASS INCLUDING SURFACE TREATMENT WITH ALUMINUM CHLORIDE AT OR JUST PRIOR TO ANNEALING LEHR

摘要

This invention relates to a method of making glass. In certain example embodiments, a major surface(s) of the glass is treated with aluminum chloride (e.g., AICI₃) at or just prior to the annealing lehr. The aluminum chloride treatment at or just prior to the annealing lehr, in either a float or patterned line glass making process, is advantageous in that it allows the treatment to be performed at a desirable glass temperature and permits exhaust functions in or proximate the annealing lehr to remove byproducts of the treatment in an efficient manner.
