What is the hazards of Polychrome Jasper?
Harm Type
Physical Toxicity
Polychrome Jasper in powdered form can be toxic due to its Crystalline Silica content.
Quartz, silica, crystalline silica and flint are non-toxic materials, but very fine dust containing quartz, known as respirable crystalline silicon (RCS), can cause serious and fatal lung disease. Lapidaries should exercise caution when cutting silica.
How to prevent the risks of Polychrome Jasper?
Avoid long-term inhalation of its dust!
Polychrome Jasper is typically non-toxic unless it's in powder form. Long-term exposure to finely ground powder may lead to silicosis. Therefore, when cutting or polishing polychrome Jasper, be sure to wear a dust mask to avoid inhaling its dust.
