more tests done...
20/24/14 sugar/kno3/wax melted the wax, mixed with the mixed powders and put in a tube
visco fuse failed to ignite the comp so a few miniutes with a cigarette lighter and it finally ignited, burned great untill it got blocked with the leftover burned stuff so i squidged it to loosen the spoil and shook it out the end, burned well for a while but blocked again and went slow.
so i tried 20/24/12 as this appeared to saturate the powder but not too much, put it in to a petri dish type tube {3" diameter and 1/2" long} doubled up the visco and tried again, fuse failed again but when i finally got it going it ignited the crappy tube and produced no smoke untill i blew out the flames
so i went back to the trusty if not violent 60/40 kno3/sugar but this time with a baffle of a penny washer glued on to the end of the tube with a glue gun it started well and the baffle was doing a good job by reducing the flame to the size of one of those jet lighters, untill the glue melted and the washer flew away..
back to the drawing board and i discovered that the screw cap of a large wkd bottle fit snugly down my tubes so i made more comp and used the bottle lid as a baffle by punchine 4, 2mm holes in the top.
upon testing the baffle did a perfect job until it was melted, and the smoke was THICK. so i am going to try a new version soon with a stronger baffle and maybe 2 with an extended tube giving a cooling chamber at the top
also will try the new wax comp mentioned above how do you ignite it? visco?

its been a while but i went off to the woods and tried the cooked with wax composition....
hmmm... not the desired efect but a very good efect none the less, i managed to make a hand held flare or emergency torch, so if anyone has a need for something that will burn with a bit of smoke and a 6 inch flame for about 4 and a half mins ie a signal flare then melt 40g of sugar with 10g of wax add the kno3 60g and pour off the excess wax. took a bit of effort to light as i think my fuse was not in the comp far enough and had to resort to a lighter, but hey! back to the drawing board
ive got an extended tube 60/40 cooked to try and one with a restricted opening {choke} to test next but i might prepare one of yours asteroid. am i right in thinking:
take 13.5gwax 20gsugar 24gkno3 {27/40/48} powder and mix the kno3 and sugar,
melt the wax pour it in to the powder mix quickly and then pack it in to a tube
?

ok, so a few people mentioned parafin wax so i just tried it, i used 40g sugar and 60 g KNO3 again and added 10 g of ground up candle, (i was told standard candle wax IS parafin wax but correct me if i am wrong) but.... i just wanted to check that i am still meant to cook up the mixture beccause it seemed to seperate in the pan and altho the wax made the mix flow like a dream and not stick all over the place i am not sure if much of it 'soaked'in to the mix i would say that maybe a quarter to half of it had to be poured off the top as i didnt want it to just take up space at the bottom of my tube.
i lit a bit of leftover i had spilled and it did seem to behave differently to my previous mixes so the wax may have had an effect but i cant be sure untill tomorrow when i can jolly off down to the woods.
