Massive Cinnabar of intense red color.
Cinnabar has a high mercury content and the rest of its composition is sulfur, making it a toxic mineral.
This mineral forms together with volcanic rocks and warm sources. In Spain there is a large deposit in Almadén, Ciudad Real.
In ancient times, it was used to preserve human bones and in cave paintings as a red pigment. Today, in addition to being an important source of mercury, it is also used in scientific instruments, electrical appliances, orthodontics...
The mineral includes a label with the name and origin and is attached to a cardboard box. 4 cm square.
*The price is per unit (a single cardboard box of the four shown in the photo)
Since the minerals are natural, you will receive a piece similar to the one in the photograph. The minerals come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the mineral. The size is approximate.
