Re: [APD] Re: OUCH! -- or- A Genuine Acid Test
According to Roger Miller last November, the weak acid
vinegar) can easily give a false negative (no reaction but
carbonates are present. The stronger acid can do so also
but it is much less likely to do so -- and what it might
miss would probably be carbonates deep in the rock that
would only leach out very slowly). For substrates, unless
the grain size is unusually large ;-), carbonates
"deep-in-the-rock" are unlikely to be an issue.
Wear gloves; handle with care.
