Re: GHS Labeling
Good morning, I have Risk Assess and Chemical Label Maker. Chem label has more detail but is good when you want to make your own label - but RA the preferred label maker for me.

Re: flame test in spray bottles??
When it comes to flame tests for juniors, I soak paddle pop sticks in saturated solutions of barium, copper, potassium, strontium and sodium chlorides. I find this is less mess. Works well for open days too.

Re: Another GHS question...

Re: weirdest things
My local Woolies always say that if I like I can buy aspro in several transactions in the one visit. They are happy to do it this way because of course they know I buy them for science. Maybe your Woolies will do this for you?
