Calcium Carbonate

Calcium Carbonate: Nature’s Ancient Resource
At GCCI, we understand the value and usefulness of this abundant resource.

With a hardness of 3 on the Mohs scale (1 the softest, 9 the hardest), Calcium Carbonate is a relatively soft rock. It is odorless, non-toxic, and in its natural form, its color ranges from off-white to pure white.

Calcium Carbonate has been used since ancient times, with one of the 7 Wonders of the Ancient World standing testament to its long history; the Great Pyramid of Giza. Constructed around 4600 years ago, the structure consists of 2.5 million blocks of limestone which largely remain intact to this day.

Throughout the next 4 millennia, Calcium Carbonate and its derivatives (mainly quicklime and hydrated lime) were widely used. Still, their applications remained limited, mostly in mortar, putties, and as a building stone.

It was not until the 1900s that its special physical and chemical characteristics, particularly in its purest form, started to be better utilized, greatly expanding its range of applications.

With more than a decade of experience, our team is committed to meeting the needs of the growing global demand.
