Han Purple and the Third Dimension Barium copper-silicate doesn’t just have archaeologists and chemists intrigued. At normal temperatures, it’s an insulator and is nonmagnetic.

Scientists have discovered that at the abrupt lowest temperature transition at which barium copper silicate enters a new state-called the quantum critical point-the three-dimensional material ...

Egyptian blue, also known as calcium copper silicate or cuprorivaite, was developed more than 4,000 years ago in Egypt and Mesopotamia.

The Clifton-Morenci mining district in eastern Arizona is sometimes referred to as the Copper Mountain mining district. But while known mainly for copper deposits, it also produced uncommon minerals.

Artisans first crafted Egyptian blue during the Fourth Dynasty (roughly 2613 to 2494 BCE) from recipes reliant on calcium-copper silicate.

Egyptian blue is considered to be the first synthetic pigment. It was derived from calcium copper silicate and was routinely used on ancient depictions of gods and royalty in ancient Egypt, like ...

More than 5,000 years ago, in ancient Egypt, a mixture of silica, lime, copper, and an alkali was heated, resulting in a bright blue compound known as calcium copper silicate. This striking ...
