No one wants cement in their eyes. Cleaning with muriatic acid. Muriatic acid (also called hydrochloride acid), diluted with water could be used to remove the cement, but since sandstone is often held together with calcite or dolomitic cement, which are broken down by acids, muriatic acid may do more harm than good.

Removing calcite from agates is an easy process. Calcite is found all around the world. It forms from rainwater and turns into limestone. Agates is a shiny, volcanic rock. A common form of agates is quartz. Calcite builds up around the agates covering the natural shine of the agates. Calcite can be removed from agates using an acetic acid solution.

Calcite is a carbonate mineral and the most stable of polymorph of Calcium Carbonate (CaCO3). The other polymorphs are the minerals aragonite and vaterite. Aragonite will change to calcite (CaCO3) at 380470 degrees Celcius and vaterite is even less stable. READ MORE; Calcite precipitation from CO H OCa(OH) slurry …
