I thought I would point out the proven fact that etching glass is sweet. It produces the same effect as frosting glass but it's a permanent change unlike frosting which can usually be scraped or polished off. The etching process actually changes the chemical structure of the glass unlike frosting which is applied on top of the glass.


The product Jen used (Armour Etch®) uses a "special formula" but it's mainly hydrofluoric acid which, when applied to the glass (SiO2), combines with the glass molecules to yield silicon tetraflouride and water (4HF + SiO2 -> SiF4 + 2H20) which both rinse away. The other result of the reaction is a disruption in the crystalline structure of the glass which turns it from transparent to semi-transparent.


Totally sweet.
