CHNO Posted February 18 Share 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. Link to comment Share on other sites More sharing options...

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?

Zumber Posted February 18 Share 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. Link to comment Share on other sites More sharing options...
