Um Rock Tumbler with 1000 frit silicon carbide grinding compound.
The only problem here is that it doesn't like to get into a deep indentations
without a tiny carrying agent. I've been know to use saw dust for this, but
it can take a lot longer to etch since the saw dust softens the tumble.

I worked for years with HF, both weak and very strong solutions in the
scientific end of glass. Trust me its nasty. It will also eat your mucus membranes
away after time.

There was a window on the wall above the sink area we used for cleaning apparatus with HF.
It became etched just from the fumes. No wonder I have cataracts and can't smell any thing!
Not to mention the skin cancer I have removed from my face occasionally.
LOL isn't life grand?
