Craft glass bottles cold besmear is on glass bottle after annealing, the single stearate, polyethylene, oleic acid, silane, silicone or other polymer emulsion paint mist, attached to the glass on the surface of a certain temperature (the bottle temperature depends on the spraying material, about 21 to 80 ° C), and form a protective layer with abrasion resistance and lubricity.

Hot applied in the system of craft glass bottle bottle shape before and after annealing treatment. Craft glass bottle after bottle forming technique of the slowly cooled to 500 ~ 600 ℃, the metal spray coating agent on the surface of the container, the formation of a certain thickness of protective film, enhance the surface strength of about 30%, and can make the bottle stands long water, water to wash.

Using organic silicon evaporation coating glass surface or all can form organic polysiloxane with silicone dipping hydrophobic membrane and aggregation (Si02). Silica film, by common silica key connected with the glass surface. After heat treatment of the organic linkers can evaporate the remaining silica membranes can be filled in the crack, the good hydrophobic can avoid active medium in the spread of crack and make the surface crack healing, not only has a larger glass strength and chemical stability, also make the glass with special optical performance and shock resistance.

Frosting is in the process of craft glass bottle cooling spraying carbon tetrachloride, or during a annealing furnace sulfur dioxide, both are available on the surface of the bottle and alkaline oxide reaction, make the sodium ion precipitation and forming glauber's salt particles on the surface of the glass (that is, the turbidity of white powdery Na2S04), after flushing in addition, due to the alkaline reduce the surface chemical stability enhancement.

Commonly used organic silicon solution with methyl fluorine silane, dimethyl dichlorosilane, two fluorine diphenyl silane and phenyl trichlorosilane, etc.
