Abstract
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., AlCl.sub.3) 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.
