Abstract

In the diffusion of ions from a contacting medium constituting a source of such ions into surface layers of a body of glass or vitrocrystalline material for the purpose of modifying at least one property of the body, the uniformity of the diffusion across the surface of the body is improved by placing the medium contacting the body in the form of a mist composed of suspended droplets of the treating medium.
