A short how to tutorial showing how I use muriatic acid to dissolve Calcite and expose the hidden crystals that are sealed inside the rock. I you have been thinking of trying this process then this short video is for you. These mineral specimens are from and old abandoned gold mine in the Marmora Ontario area and are full of micro Arsenopyrite Crystals just waiting to be revealed. Soon I will do a video of how I use Iron Out to remove stains from my mineral specimens.

Collect, rockhound, explore, dig and hike at your own risk.
