Barium copper-silicate doesn’t just have archaeologists and chemists intrigued. At normal temperatures, it’s an insulator and is nonmagnetic. Along with its many fine properties ...

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. As reported by Focus Online, it was produced artificially by ...

Gladiator has received results for a recently completed gravimetric survey at the Little Chief Trend that has highlighted ...

For being the world’s oldest known synthetic pigment, the original recipes for Egyptian blue remain a mystery. The approximately 5,000-year-old dye wasn’t a single color, but instead ...

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

M ore than 5,000 years ago, in ancient Egypt, a mixture of silica, lime, copper, and an alkali was heated, resulting in a ...

Emphasis was placed on copper silicate ore from a small schist deposit. Proving unprofitable, the smelting operation was relocated to Globe, with upgrades including two operational 30-ton furnaces ...

In fact, it seems likely that copper smelting stimulated not only glazing but the production of glass itself, as well as the pigment known as Egyptian blue, which is a ground-up copper silicate glass.
