Care and handling

This stone contains native sulfur, which is soft, flammable, and gives off irritating dust and fumes when ground, scratched, or heated. Do not grind, sand, or burn it, and avoid breathing any dust. Wash hands after handling, and keep it away from children, pets, and open flame. Never place it in the mouth, in water, or in gem water or elixirs. Clean only by gently wiping with a dry or barely damp cloth, and avoid heat, steam, and strong chemicals.

Individual experiences with Sulfur Quartz vary, and it is best treated with respect for the material as well as the meaning. Use it as a symbol of focused intention and always follow the safety precautions.
