75:15:10 with JUST charcoal will be a lot sweeter than any sugar comp. especially if you can get it really fine, most KNO3 doesnt come too fine. get a rock tumbler and throw in a dozen marbles, that works great. leave that on for a couple hours...the finer the powder, the better the blaze. dont expect to make some really explosive powder though, the mix ratio for that is like...molecular precision. 67:23:10 works in my rockets with sugar. but burned pine cones are a ton better.

potassium/sodium nitrate and ammonium nitrate is also sold at http://www.gardenchemicals.co.uk just thought you might want to know thats where i got my first batch of potassium nitrate

my ammonium nitrate comes in 25kg bags also, but it`s more than I can use on my land, so normaly me and some friends share the cost and the product, I`ll prolly use no more than 5 kilo a season, so it pays to share

 

and NO, I`ll NOT supply it, before anyone asks!

im not botherd about you supplying it but where do you get yours from my next door neighbours a farmer so if i ask him he just gives me about a couple of kg which lasts me months,he is a brilliant neighbour

I`m on the commitee of an allotment association, I can get alsorts

lucky bugger!

can't you get arrested under suspician of terrorism, if you buy large amounts of ammounium nitrate?

i dont think so unless its a new law but i dont buy large amounts i rarley use it if so its yt who should be worrying

yup, if it was LARGE amounts (25kgs not large considering the circs). not only that, there`s no charges that could be made to stick (to us anyway) we have a genuine use and no terrorist affiliations (that I know of)

 

so yeah maybe I`de get questioned "Why do you have a 25kg sack of (whatever) in your shed" but they`de soon notice that I`m hardly the terrorist type and have good reason for such materials

 

not only that, but my shed`s half kitchen anyway (even got a little spice rack in there)

i dont think so unless its a new law but i dont buy large amounts i rarley use it if so its yt who should be worrying

LOL, we regularly have the police on site (vandals) I`ve stood next to a bag of the stuff smoking a cig and had a good old chat with them, they KNOW we`re not the problem

potassium perchlorate works awesome as well, but i have no idea about the ratios with that as the oxidizer. mostly its used in solid rocket fuels. i think NASA used it on the booster stages for the shuttle.

Umm, doesn't potassium chlorate/perchlorate + aluminum powder make flash powder in a ratio of about 7/3?

yes it does as well as using aluminium you can use magnisium but perchlorates are safer then chlorates and guess where you can get them from except united nuclear....http://www.kno3.com

Doesn't magnesium produce a bright light effect with a lesser *boom*, and aluminum a less-bright effect with more *boom*?

i carnt say i have ever heard of that magnisium is better because it gives a much brighter effect the booming sound is the cardboard tube breaking so i would say no to the boom effect but yes to the brightness effect

yeah, oxidizing mg is some fearsome stuff

potassium perchlorate works awesome as well, but i have no idea about the ratios with that as the oxidizer. mostly its used in solid rocket fuels. i think NASA used it on the booster stages for the shuttle.

they use Ammonium Perchlorate and alu with a rubber binding agent
