A suggestion borrowed from the craft of decorative glass etching would be to mix the HF with a biflouride, such as ammonium biflouride, which will leave a frosted surface. Unfortunately I do not know the proper mix ratio, but checking with the glassblowing shop in your Chemistry department may yield the answer, or look up glass etching in a public library under arts and crafts.
