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.
