Notes:
In a closed tube, gives off water at a fairly low heat. Upon increasing the heat it produces an arsenic coating in the neck of the closed tube. This is very characteristic, and together with its appearance is sufficient distinguish it from willemite, bustamite, rhodonite, rhodochrosite, or friedelite.
Slowly decomposed by hot hydrochloric acid leaving a residue of granular silica.

No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
