Hello to isogeochem watchers,

I have attempted to extract oxygen from epidote using the Ni-vessel and
BrF5 method. I have heated the vessels at 500 C overnight. From my review
of literature, no special treatment has been described for epidote oxygen
extraction using the BrF5 method. I have not produced more than 5% of the
expected yield of O2. X-Ray diffraction confirmed it was epidote.

Is there a trick I missed for epidote?
