Realgar - Wikipedia

Realgar, α-As 4 S 4, is an arsenic sulfide mineral, also known as "ruby sulphur" or "ruby of arsenic". It is a soft, sectile mineral occurring in monoclinic crystals, or in granular, compact, or powdery form, often in association with the related mineral, orpiment (As 2 S 3).It is orange-red in color, melts at 320 °C, and burns with a bluish flame releasing fumes of arsenic and sulfur.
