What element can be used to write letters and drawings on glass?

Fluorine will etch glass. Hydrofluoric acid is used to create etchings with pictures, words, etc.
For simple etchings, tape can be used to resist the acid. Complex etchings can be made with wax or epoxy to resist the effect of the acid and those substances then have to be removed from the glass.
