摘要：
Methods for increasing the hydrolytic resistance of a glass article are disclosed. According to one embodiment, the method includes providing a glass article with a pre-treatment hydrolytic titration value. Thereafter, the glass article is thermally treated at a treatment temperature greater than a temperature 200C less than a strain temperature of the glass article for a treatment time greater than or equal to about 0.25 hours such that, after thermally treating the glass article, the glass article has a post-treatment hydrolytic titration value that is less than the pre-treatment hydrolytic titration value.
