hi everyone, I'm having difficulty with the zinc here in oz. I have calcined it but still no crystals. I have some very old zinc, which works, but recently purchased zinc results in no crystals forming, very muddy glaze....can anybody help?

Hi berryed4art
I have been having this problem here in OZ for years Some years go I was able to buy zinc oxide dense from pottery suppliers. It was a grey powder Now they sell a white powder which they say has been calcined to the manufacturers specifications. Cant get it through an80mesh sieve even after using a mortar and pestle. I now buy zinc oxide dense(the grey stuff ) from the USA. Not helpful if you only need small amounts. But the postage does compare well to OZ.
Cheers
Nell
