Other InformationHide

Notes:
Soluble in water
Special Storage/
Display Requirements:
Although calciodelrioite has a structure that is very similar to rossite, with which it is commonly associated, rossite is almost always partly to completely altered to the lower hydrate, metarossite, whereas calciodelrioite exhibits no evidence of such alteration.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
