Smokelvr Posted May 29, 2022 Share Posted May 29, 2022 I read somewhere in russian literature about so-called "white match" which is made like "black match" but instead of BP composition of phenolic resin + potassium nitrate is used. I used the following composition: Phenolic resin - 30%Potassium nitrate - 70%solvent - ethanol The burning rate of such fuse is about a half of black match and it is more resistent to humidity and moisture.78% KN20% Phenolic Resin2% Hexamine+1% red iron oxide I know it has excess KN, but I don't know the burn chemistry for Phenolic resin, and figured the excess nitrate would be used by the string. Hexamine and PR, properly combined makes a formica countertop like substance (pressure + heat + process conditions = bakalite) that's a fast or faster than my blackmatch Link to comment Share on other sites More sharing options...
Smokelvr Posted May 29, 2022 Author Share Posted May 29, 2022 Also, it seems to get in the cotton string better than BP, I should use methanol, ended up using ethanol + acetone, the string was put in a zip lock bag and shaken with dry composition then wetted and drawn out just running between gloved fingers, there was some composition evenly covering the string but not like you need for blackmatch. I surprised myself with how well it works Link to comment Share on other sites More sharing options...
tortoise Posted May 30, 2022 Share Posted May 30, 2022 What % ethanol and what % acetone? Link to comment Share on other sites More sharing options...
Smokelvr Posted May 30, 2022 Author Share Posted May 30, 2022 Didn't pay much attention to the amount but enough to make a pancake batter like slurry, Alcohol was some 91% rubbing I grabbed from around the house, need to get more methanol Interesting is that bare it burns about twice as fast as my black match but when I tried it in quick match it was about half as fast? Which is still quick but noticeable slower, also stinks to high heaven Link to comment Share on other sites More sharing options...
