Removing shell deposit from a rock.

Post by Mbunro »

This is one of a few rocks I collected on a trip up to Broome last month.
It's no masterpiece but of all the rocks I collected I figured this would be the easiest to learn daiza making as it has a fairly flat lower edge, that and it looks like harambe riding a cloud if youve had a few beers.. I'm enjoying the process so far but am now stuck untill I find a band saw to use..

In the meantime I figured I should have a go at removing the white shell deposits all over the rock.. I have tried a wire brush on the dremmel on the unseen bottom edge but it only gets off the chunky pieces and leaves marks which I'd like to avoid.
Wondering if anyone has any tips on removing them without damaging the rock?Image

As long as your rock wont be damaged by the acid you can soak it in vinegar. The vinegar will desolve the Calcium Carbonate in the sea shells. Just do a test on the rock first somewhere where it wont be seen if it does reacts to the acid.
