Other InformationHide

Thermal Behaviour:
Before the blowpipe sinters to a gray, bubbly mass, melts at 745° to a gray-brown glass with n = 1.623.

The mineral loses 11.9% to 160°, 13.4% to 300°, 15.5% to 340°. The DTA curve shows an endothermic effect at 160°, and a slight exothermic effect at 700°.
Notes:
Insoluble in H2O. Slowly decomposed by dilute HCl or HNO3 giving skeletal silica.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
