Abstract:
A method of reworking lithium containing ion exchanged glass articles is provided. The method includes a reverse ion exchange process that returns the glass article to approximately the composition of the glass from which the glass article was produced, before being subjected to ion exchange. The reworked glass articles exhibit a K2O concentration profile comprising a portion wherein a K2O concentration increases to a local K2O concentration maximum.
