Calcium - known to every schoolkid as some vaguely healthy substance in milk and cheese - is an element whose true nature is much less well known to most people. The metal simply cannot exist in nature uncombined with other elements because it is too reactive; that is, too willing to pair its atoms with other atoms to form molecules.

While in free form it is unknown to so many its molecules sure aren't: CaCO3 gives us both chalk and marble while the slightly different CaSO4 is much better known as the sheet rock that lines most American homes. Your very bones are a brew of calcium phosphates.

Calcium may love the company of other elements but here we starve it of company that you may enjoy seeing a rare glimpse at this metal. Here is a generous sized sample that comes permanently embedded within a 5cm block of polished Lucite acrylic.
