Other InformationHide

Notes:
Highly adhesive to moist surfaces. When breathed upon, it has a strong earthy smell. When put into water, it does not become translucent nor fall to pieces but gains considerable weight.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
