Hi All!
I wonder if any of you have any advice for me about what the best =
temperature might be for calcining zinc oxide?

Hi Erin,
Since you are only dealing with damp material rather than chemically bound H2O, any temp from ~250F to ~800F will
work. Higher, you'll start to get fuming - probably not what you want, and toxic besides.

I just throw mine into a regular bisque, ^04 or so.
Seems to work OK.

From Craig Martel I learnt to calcine the Zinc in 815C. I do it either
in paperclay dishes that allow me to fire high faster than normal and
save the cost of the slow firing or add to the bisque of the crystal
that I do to this temp. Still there are some lamps. I sieve the zinc
through a kitchen- strainer and the last sieving with the glaze.
