Calcite Plaque

Calcite Plaque from France

This plaque was produced by allowing natural spring water, rich in minerals, to flow over
a mold for about 8 months. When this mold was removed, this beautiful artwork,
composed of calcium carbonate (in the crystal form known as calcite) was the result.
Calcite often makes up stalactites, stalagmites, and flowstone formations in caverns.
These plaques can reach up to 1cm (0.4 in) in thickness in 8 months. At this rate,
50 feet of calcite could accumulate in 1,000 years. Fast-flowing water, with lots of
minerals in solution, is all that is necessary to form calcite quickly. This is the case for
the development of formations found in caverns too. They can form quickly with lots
of flowing water containing the appropriate minerals.

This plaque comes in a protective box that you can also display it in.
