Thanks mate, will give it a go and fingers crossed it turns out to be perc. I have two batches, one from a good source and the other from a not so good source. For safety rather than wanting to know if i have been ripped off!

Drip a very small amount of H2SO4 onto a very small quantity of the mystery powder - if you get a reaction it ain't KCLO4 (or is, but contamined with KCLO3) and likely to be the O3. Not the most scientific, but it will show you that it ain't safe if it is O3.
