Stripping a primordial operation
The stripping operation is essential, French standards (ban on phthalates in the manufacture of glass), and the glass industry in general require the lubrication of glass molds in high doses. During the finishing operation, this grease can harm your decorating operations. Stripping therefore consists of degreasing the glass. This operation can also be used in the event of glass exudation (stains or haze formed on glass stored for too long or dedicated to export in a humid area).
An alternative is also called sulphating, here your glass has a powerful protective layer against humid tropical environments.
