| acid etching |
Acid etching is the selective dissolution of a surface (usually the tooth enamel) by a dilute acid. In the case of the tooth surface, this causes demineralisation of the enamel leaving a clean and more mechanically retentive surface layer, thereby improving the bonding to filling materials. The acid used is generally 30 to 50% Phosphoric acid.

A method for decorating glass. The glass surface is covered with wax, the desired design is inscribed in the wax, and then hydrofluoric acid is applied. The acid will only corrode the areas that are not covered by wax. This process produces a flatter design than engraving.

The process of etching the surface of glass with hydrofluoric acid. Acid-etched decoration is produced by covering the glass with an acid-resistant substance such as wax, through which the design is scratched. A mixture of dilute hydrofluoric acid and potassium fluoride is then applied to etch the exposed areas of glass.

This is a technique for decorating glass. First the glass is covered with an acid-resistant layer. Then a design is scratched into the protective layer. Finally hydrofluoric acid is applied to "etch" the pattern into the scratched areas. The area covered with the protective material will not be affected by the acid.
