Insoluble or only slightly soluble in most cold dilute acids and bases. Decomposed by hot 1:1 HCl and cold acetic acid leaving a colorless residue.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
