I have found this site http://www.americanelements.co.uk/. it sells almost everything form kno3 to cesium. Has anybody used it before?

Talking of rare chemicals, anyone know of any cesium or rubidium compounds (preferably carbonate ) going at a reasonable price?

Where do you get cesium or rubidium metal. I am quite good at making salts from these so would prefere to make my own than buy them. Many thanks

Hi James. It's good to see another scientist on the forum!

Regarding the dream of making a complete display, this is not currently possible. The UKPS aims to lobby the HSE for a waiver allowing small scale manufacture, so I do suggest joining the society to support this.

The reference to the unlicensed manufacture of 100g composition comes from the UK MSER regulations, intended to facilitate university and other research. Yes, you can legally mix this much composition. No distinction is made between BP and other fuel/oxidiser mixes, so this is a total mass including any additives. You are not allowed to store or practically 'deploy' but can test it. I think you could successfully argue that consolidating it into a tube is a necessary part of the test, as would be repeated attempts at improvements over time. As you say, 100g is plenty when starting out (see my 12g titanium gerb in the fountain formula section as an example).

Within the complex UK legal framework, the amateur pyrotechnician is certainly working close to the limits of what is possible. The UKPS is working hard on a guide to this. In the meantime, be open and honest with the powers that be, take all possible safety precautions, join the society and enjoy the hobby - cautiously!

I would just like to add that yes it is legal to make 100g of bp without a licence it is rather dangerous. Storing bp is very risky due to accidental ignition or its quality deteriating. I do advise all who are considering this that they think again!

If you want to see how powerful/dangerous flash can be, just check out this thread i put up a while back

wow that was nice but yea i see what you mean thanks!

c-lab, 1stly as Wyvern mentined this is a tooling thread. The questions you are asking are covered in different threads. Search and ye shall find

"2ndly, you are obviously new to pyro, and as such, i strongly reccommend, if you want to keep your fingers where nature intended, you stay away from flash of any kind.

Yes i am new to pyro. Lol didt know it was that powerful but thx
