Thread: Making Black Powder

I substituted out the willow for totara and my powder got denser...if lived in north island tawa would be interesting to try as its rather similar to willow... I tried totara as have tree on front lawn and wee branch had blown off and was dry
looking at burning characteristics of willow burns fast/burns clean with little ash/sparks if burnt green/is light in weight/easy to ignite....then thought about our native timbers and both tawa and totara met same criteria.
