What are the laws on cannons in the UK? p.s I'm not sure about sulphur free BP, but a standard mix is 70.5 KNO3 : 29.5 charcoal.

These were a few cases found on the BBC website, they are relevant to the fact that these guys were probably pyros. If anyone finds any further news about the fate of the guys in these cases I would appreciate it if you could post them, thanks! Just type in "Chemicals Arrest" or something similar, and sift through the page. . I also understand that dangerous objects can be made out of easily avaliable chemicals, and many everyday chemicals can be explosive under the right conditions. But thats not really the point of this topic. Any replies are appreciated.

Well I wouldn't make large quantities, or store it since you need a licence to store it. Thanks to everyone who has replied!

So would a potassium nitrate, sulphur, aluminium, and boric acid mixture of flash powder be a pretty stable form of flash powder?

Currently to my best knowledge (may not be perfect!)

Fuse is legal

HOWEVER

Putting it in the post is definitely NOT lawful so how are you going to get any.

The slow fuses typ Visco, should be restricted supply items. It is the supplier's choice and responsibility to allow them only to people whom he considers competent. These should be stored to MSER in approved storage. You HAVE read and understood MSER havent you!

Medium speed fuse typ quickmatch and sticky match are again products on restricted supply from a licensed seller. They will usually only supply to professional users with licensed storage and insurance.

Fast fuses typ det cord (cordtex) -very strictly controlled to professional users with specific official police permission and full insurance and storage. ALSO these have no place in fireworks they can overlap from industrial blasting into SFX work

Electric igniters are a UN class of their own and can be bought from some high end firework shops, (the bought ones are much more reliable than made ones)

IN ALL CASES Possession will be looked at according to the likely end use. Also consider that storage should always be to MSER and secure the items against theft.

I know about MSER regulations, I only use the fuse for very small arial shells, and only I have very small amounts of fuse. Thanks for your help, any other posts will be appreciated.
