Dear Clayart members,
Ron suggested that someone may have had this situation and possibly had
suggestions. Please advise if you have successfully "reclaimed" hard zinc
oxide.
Thanks,
Anne

Hi Anne,
Well I have tried to find the relevent information in my library but still
don't know what temperature is recommended - I think what you did was
right
but - the one reference I found said you have to regrind it.
If you want me to ask the list just let me know - someone must have this
figured out.
Regards,

Ball mill it (dry).
I've done it.
Mine was not in big chunks, but gravel size pieces.
Didn't take very long, in ball mill time,
just a few hours.
Best wishes,

So, it seems that some force must be applied to this zinc oxide: thermal?
Chemical? Mechanical? Just yesterday I mixed two glazes that contain zinc
oxide. What was available in the studio was a couple of solid chunks. I used
an old screwdriver to make smaller chunks and a mortar and pastel to get a
nice fine powder. I know that this won't be the way to go for the quantity in
question, but some re-grind (mechanical) process seems like the only practical
way. (I'm just getting this mental picture of someone in a pickup truck
driving over zinc oxide. That's the way some folks de-hull black walnuts.)

Hi Anne:
Ball mill it if you have one. If not the best I have been able to come
up with is smash it up with a hammer as best as possible, dry seive through
a series of smaller mesh (wearing proper protection), calcine with your
next bisque, re-seive (protection again), store in air tight bags (this
stuff sucks up water vapour like a magnet).
It works but it is a lot, I repeat, a lot of work. Good luck!!!
Regards, Marc

I helped Mile Hi Ceramics buy a truck load of unused Bell Hammer Mills
several years ago ( they were from a fellow who tried a business of making
insulation from newspapers a customer would save for quite a while - then
he would send out one of his trucks and they would grind the paper and add
the appropriate binder and spray it into your attic. Needless to say he
didn't last long ) I'm sure Zach would sell you one for $40 or $50. You
could add a motor and grind anything to your hearts content. They really
are sweet little machines and are still being made somewhere in Neb.
Hope it helps.
