Fluorescence of ParatimroseiteHide

Non-fluorescent.

Other InformationHide

Notes:
In dilute HCl paratimroseite immediately decomposes, turning opaque white, and then the residue slowly dissolves.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
