Abstract
Abstract A process for treating a glass container which has been subjected to a hot and metal oxide treatment which comprises applying to the glass surface a coating of oleic acid, palmitic acid or steoric acid whilst the glass is at a temperature within the range from 90*C to 130*C, and then applying an insoluble organic coating whilst the glass is at a temperature within the range from 90*C to 150*C.
