Zinc Powder
Posted: 23 Jul 2015, 09:43
Hi Everyone,
Just wondering....Is Zinc Powder a teacher only chemical? I have looked in CSIS and could only find Zinc Dust (which to me is the same as Zinc Powder).
I realise Zinc Metal, Granules and Foil are all ok for years 7-12, but concerned about the powder???
Thanks
