What type of reaction is acid glass etching?
By Acid glass etching i mean when Hydrofluoric acid is used.
chemical equation:
SiO2(s) + 6HF(aq) → H2[SiF6](aq) + 2H2O(l)

Also is there another chemical equation to acid glass etching?

It is a classical example of neutralization, where you have a base (silicon dioxide) and acid (hydrofluoric acid). The second part of the reaction, after neutralization, is complexation of the formed silicon tetrafluoride.
