CoSHH sheet for the Copper oxide has now come through:

98% Cu2O is all it says wich isnt too helpfull but I can assure anyone that Ive used it myself and its the real deal for colours and crackling micro stars and thermite.

Let me know who is interested

[Creepin_pyro]

Thanks for going to the trouble of checking the CoSHH, but I think I'll leave it. I've only ever been pleased with the results from much purer Copper Oxide (for colour stars).

[leosedf]

I've used cooperman's copper oxide in colored stars. Works fine for me

[cooperman435]

And the antimony trisulphide has arrived too now. £8.50 per kg or £8 if you buy a few at once.

25 kg total

roughly 15kg already shifted so 10kg remaining

As always it depends what the other 2% is! If it's copper or copper sulphide, no probs, but you wouldn't want any sodium or maybe calcium in there! In commercial firework manufacture, relatively impure chemicals are sometimes used not least on cost grounds as long as they have the "right" impurities.

Wow, expensive indeed!

he does it whenever the product is out of stock his ball mill is probably damaged.

Ball mill problems are to blame. I think Steve has almost remedied the problem.

his ball mill is probably damaged.

Try absolutly fu*ked! The motor blew, then there were problems getting the right pulleys, oh and the motor had nicely placed fixings that were used to build a part of the surporting structure (which now has to be replaced also), it will look very differnt once fixed.

[cooperman435]

Its reportedly working now as Ive just made and shipped him a new pulley.

Prices should fall soon lol
