In Topic: hexamine

The reason for the use of hexamine is that it dramatically increases the size of the flame envelope. Thus it has two functions, to increase the size of the light source and to reduce the temperature as the heat is spread over a larger volume.

It does work, my best blue to date had hexamine in it.


Would you mind sharing the forumula? Pleeeeeease?! :D

I would think the bp clay mix would act like a cheap and easy delay.


On pyroguide it does state that the Chinese commonly use clay mixes as delays

I tried emailing them to see if they ship to Northern Ireland, but either no response or it got caught in my email junk filter. Anyone know?

The KNO3 prices are stupid, I got mine @ £3.50 for a kilo plus £3.50 P&P from a different source. May stay clear then, was only looking potassium perchlorate. It's £18 for 500grams, does that sound OK? Are there any other (reliable) suppliers of this chem that any of you have personally used?
