Calcium Element Cube

Calcium's atomic number is 20 and its symbol is Ca. Calcium is a dull grey metal that is often associated with milk and healthy bones. While it is true that calcium plays a major role in bone health, pure calcium metal would be a major hazard to ingest since it readily reacts with water creating heat and hydrogen gas. Calcium is the third most abundant metal in the earth's crust behind iron and aluminum. Tens of thousands of tons of calcium are mined every year in the form of fossils and minerals such as limestone.

The sample of calcium in our element cube displays is pure calcium pellets loosely encapsulated in a glass ampule.

Unlike many of the knock-offs found online, our element cubes contain the actual elements, which is perhaps the most important feature of the display!

Superior optical clarity, careful placement of the elements in the artwork, and real, pure elements are what set us apart. This is the highest quality and most complete element collection on the market.

We manufacture our element cubes here in the US using Lucite acrylic which does not yellow over time and is the most optically clear acrylic. This is the perfect gift for the science or chemistry lover in your life. Get yours today!
