Chemical used for glass etching

Hi,

Flourine is the element. When combined with hydrogen to form hydrogen fluoride, and the dissolved in water to form hydrofluoric acid.

As hydofluoric acid, it will etch glass.

Hydofluoric acid has a single hydrogen atom and one fluorine atom, physicaly its like hydrochloric acid, a clear liquid.

The formula for hydroflouric acid is HF.

Search Wiki for "hydrofluoric acid" to get more detail.

Hope this helps,

Mike
