Quetes61 Posted September 4 Posted September 4 Dear fellow pyros ,recently I was visiting a firework factory in Mexico where they were having difficulty in acquiring visco fuse so they managed to get a machine,they made beautiful fuse however have no idea what formula to use to adjust burn time from our standards like 1second 3-5 seconds and 28 per foot all of these are perc formulas as they burn much hotter for better ignition, I thought possibly some of you fine gentleman would have some formulas stashed to help them out ✊
