Hi, and thanks in advance.
So hobbyists use hydrofluoric acid to etch glass and make pretty designs on it. The acid reacts with SiO2. Does borosilicate glass (Pyrex, laboratory glassware) contain similar or appreciable levels of SiO2, and will the acid be able to etch it? Would more acid / longer exposure be necessary?
Thanks.

Hense, Hydroflouric needs to be stored in a non-glass, usually polymer, container.
Pyrex is mainly designed to be heat resistant, because of it's low CoE. I wouldn't think it is any more resistant to Hydroflouric than any other glass.
It is something I would try on a test piece, though.
