How to Make Eggshell Calcium (and Why You'd Want to)

Feb 25, 2018  This frees up the calcium ion to be absorbed in the gut. And in fact, studies have proven that amino acid chelated calcium is LESS absorbed than calcium carbonate because the calcium is less likely to separate from the amino acid and the transporter for calcium is designed to absorb the free ion, not calcium chelated to an amino acid.

Chalk (Calcite) - Natural Pigments

Dry grinding limestone reduces it to a powder without destroying its particle structure, which is important in making strong chalk grounds and providing tooth on the surface of the grounds. The larger particle size of our chalk (when compared to precipitated chalk) keeps oil absorption low, which is ideal when adding it to oil paint and mediums.
