Orpimente Massive.
Known since ancient times, orpiment is an arsenic sulfide with a beautiful golden yellow color. Alchemists fused it with copper, hoping to obtain silver.
Formerly it was used in medicine and as a pigment for painting, but also to obtain, by burning it in the air, arsenic anhydride, a toxic substance used to cause poisoning.
ATTENTION: It is a toxic mineral. Use under the supervision of an adult and wash your hands before and after.
