Abstract
Glass bodies formed from a vitrifiable composition are given a desired coloration by introducing a reducing agent into surface layers of the body, during or after its formation from a molten composition, and the then the body surface into contact with a diffusion medium composed of a mixture of a salt furnishing reducible metal ions which are capable of being reduced by the reducing agent, and a diluting agent constituted by a salt of another metal, the body being subjected to temperature conditions such as to cause the reducible metal ions to diffuse into the body surface layers and to there be chemically reduced by the reducing agent.
