Claim Text:
1. A method of chemically strengthening a glass article which comprises at least one mobile ion, the method comprising subjecting the glass article to one or more ion-diffusion processes in each of which the glass article is subject to a predetermined temperature versus time profile, wherein at least one profile is at least partially based on a computer-implemented model for the spatial distribution as a function of time of the at least one mobile ion within the glass article, said computer-implemented model comprising moving mobile ions within the glass article based on a random value, wherein the computer-implemented model discretizes at least part of the glass article into a plurality of layers internal to the glass article and at least one interface layer at an edge of the glass article; and wherein the interface layer controls movement of the at least one mobile ion between the glass article and the molten salt bath.
