Mineral specimen prep services?


Recommended Posts

I used a local source on some of my first specimens but stopped after I had to ask for the gold that dropped out of the rock during the HF bath.

"Oh, you wanted that gold as well?". Uh, yeah, that 3 grams would be nice to have.

Also, used tongs on the specimen as it was retrieved from the solution, knocking even more gold from the piece.

You can use Teflon tape to wrap or tie the specimens for dunking in the hfl acid. Teflon is impervious to hfl acid.

Could also weave a specimen "basket" with  using Teflon tape.
