History - Calcium Carbonate

The Calcium Carbonate allowed for a stronger bond and helped these early groups create beautiful lasting structures. Humphry Davy prepared the pure form of Calcium in 1808 by pasting a electric currant through melted calcium chloride. Humphry Davy lived from 1788 through 1829 and was a major contributor to the field of elctrochemistry.
