Re: sand vs gravel

[Mike & Diane Wise <apistowise@fgn.net>]

I agree, muriatic acid (industrial grade HCl) is the way to go. I used this
on large blocks of limestone containing silicified fossils while working on
my MSc thesis. It works like a charm. Just be sure to follow all of the
warnings that come on the bottle - particularly using it in a well ventilated
(preferably open) space. The vapors can destroy cotton and many synthetic
fabrics in no time at all. I had a complete collection of 'holey' shirts by
the end of my project. Inhaling the vapors isn't very pleasant either!
