Question 1

What is calcite and what makes it special?

Accepted Answer

Calcite (CaCO3) is the main component of limestone, marble, and chalk - one of the most common minerals on Earth. Its distinctiveness lies in its extraordinary variety: its natural form can be solid, crystalline, translucent, or vividly coloured. Iceland spar calcite exhibits double refraction, a striking optical phenomenon.

Question 2

How many pieces and what colour varieties does the set include?

Accepted Answer

The set contains approximately 32 natural calcite samples with a combined net weight of 4 kg. The colours can vary: white, yellow, orange, and other natural tones. Since these are natural, unpolished minerals, the shape, size, and shade of each piece will differ.

Question 3

Is it suitable for school education?

Accepted Answer

Yes, calcite is an outstanding educational mineral: its double refraction can be dramatically demonstrated, and its reaction with an acid solution makes for an easy and engaging experiment. The set of approximately 32 pieces provides enough for distributing to a full class for individual examination. The Moroccan samples are natural, authentic specimens.
