In turn, this affects calcite’s reactivity. Thus far, the influence of synthesis approach on the internal structure of crystals has received little attention.

The eyes belonged to an extinct group of animals called trilobites, and their eyes were made of hard crystal, a mineral known as calcite – a strange little quirk that gives us a window into how these ...
