ATM ACID ETCHING OF GLASS

["Sidor . Kurt" <KSidor@drc.com>]

List,

I am curious to try a glass etching experiment using hydroflouric acid.  Yes
I know the dangers and risks.  My experiment would use a very (?) dilute
solution, 99.5% water and only 0.5% HF.  I am wondering if there are any
chemists out there with any opinions as to how dangerous HF is diluted to
this level, I am well aware of the dangers at higher concentrations.  Thank
you very much, please respond off list.

Sincerely,
