tommy4543 Posted February 18 Posted February 18 hello everyone i made my first visco machine as my black matches kept going out, i made some visco with just my 75/15/10 mix and it works its just very slow is there any comps out there that i can use nitrate as i cant easily get potassium perchlorate or any of the other stuff people normally say to use for visco. thank you if you can help
CHNO Posted February 18 Posted February 18 Use a different charcoal and add some Fe2O3. 70% KClO4 / 30% charcoal is certainly also a good mixture. You can also mix 70% KNO3 with 30% sugar and soak a string with a concentrated solution.

You can also mix 70% KNO3 with 30% sugar and soak a string with a concentrated solution. Could copper oxychloride be a substitute for the Fe2O3? I know that both of them are used in whistle fuel comps, and both of them are catalysts, so maybe the copper oxychloride would also work? Edited February 18 by PillaDoubleG
Zumber Posted February 18 Posted February 18 This topic been discussed recently. Pyrogreezer have already posted visco formula and he has very vast experience In fuse making. You must need goid quality bp ( hot charcoal ) For visco he mentioned blend of 70 percent 7F with 30 percent mead D. As granulas burn faster ( propogative burning ) It could solve your problem. Perchlorate based can be friction sensitive and impact sensitive.
