Abstract
There is formed a silicon-base antimigration barrier layer by projection, on a hot surface of a glass object, in an unconfined ambient atmosphere from a gaseous mixture comprising neutral gas, a silicon precursor, typically a silane, between 10 and 60% of ammonia and preferably less than 5% oxygen, the ratio of the oxygen and silane contents being comprised between 0 and 4. It is useful particularly for the treatment of sodium-calcium glass receptacles to prevent migration of ions into liquids contained in the receptacles.
