Frosted glass

Frosted glass is a glass which has been rendered opaque through a process which roughens or obscures the clear surface of the glass. Frosted glass can enhance the beauty of windows, glass doors, or glass cabinets. This technique adds warmth and style to any décor.

Frosted glass or opaque glass is produced by the sandblasting or acid etching of clear sheet glass. It has the effect of rendering the glass translucent by scattering of light during transmission, thus blurring visibility while still transmitting light.

The frosted glass effect can also be achieved by the application of vinyl film, used as a sort of stencil on the glass surface. "Photo-resist” or photo-resistant film is also available, which can be produced to mask off the area surrounding a decorative design, or logo on the glass surface. A similar effect may also be accomplished with the use of canned frosted glass sprays.

Glass frosting can be accomplished on glass of any colour, and can look quite striking and distinctive.  Care should be taken while working with acid to produce frosted glass. Eye and face protection should be worn when making frosted glass.

Various Frostings

A frosted appearance may be given to glass by covering it with a mixture of magnesium sulphate. When this solution dries, the magnesium sulphate crystallizes into fine needles. Another formula directs a strong solution of sodium or magnesium sulphate, applied warm, and afterwards coated with a thin solution of acacia.

A more permanent "frost" may be put on the glass by painting with white lead and oil, either smooth or in stipple effect. The use of lead acetate with oil gives a more pleasing effect, perhaps, than the plain white lead. If still greater permanency is desired, the glass may be ground by rubbing with some gritty substance.

For a temporary frosting, dip a piece of flat marble into glass cutter^s sharp sand, moistened with water; rub over the glass, dipping frequently in sand and water.

If the frosting is required very fine, finish off with emery and water. Mix together a strong, hot solution of Epsom salt and a clear solution of gum arabic; apply warm. Or use a strong solution of sodium sulphate, warm, and when cool, wash with gum water. Or daub the glass with a lump of glazier^s putty, carefully and uniformly, until the surface is equally covered. This is an excellent imitation of ground glass, and is not disturbed by rain or damp. The production of imitation frosting entails little expense and is of special advantage when a temporary use of the glass is desired.

Manufacturing Process

The frosted glass production requires a thorough cleaning of the glass surface before beginning the frosted glass process.

Frosted glass frosting formula is mixed with wallpaper paste, white powder paint pigment, water, and acid free PVA glue. All ingredients are mixed well, except the glue until having a pudding texture for the frosted glass project. Once this texture is achieved, a drop of glue is added so that the mixture will adhere to the glass.

The stencil should be placed on the glass, using painter^s tape to secure it to the glass surface. The frosted glass mixture is applied using a stiff brush over the stencil. This is continued until all of the areas of the glass that we want to turn into frosted glass have been coated.

Applications

To obtain visual privacy while admitting light.
Decorative patterns may be imposed upon otherwise plain glass by using wax or other resist to retain transparent areas.

 A sheet of frosted glass is an excellent privacy aid because it admits light without allowing people to see through it. In medical offices and bathrooms, the use of a curtain or blinds would make a room gloomy and unpleasant to be in. Frosted glass, on the other hand, keeps a room bright and friendly while still allowing people to be comfortable. People may also use frosted glass for privacy in entryways in urban areas.

Commercially produced frosted glass is usually frosted with acid etching or sandblasting. Acid etching is used to make frosted glass with a pattern. Patterned glass sometimes appears in ornamental windows, as well as in glasses, mirrors, vases, and other glassware around the house. The pattern can be simple or extensive, and it may include floral or geometric elements. Sandblasting is used to frost an entire sheet of glass, for installation in places like bathrooms and other areas where people might want privacy.
