shagaKahn Posted April 2, 2011 Posted April 2, 2011 Find repeated reference to this item and even a few formulae using NC for the promoter and various Ba and Sr salts for color. Love the idea of a smokeless colored fire. Anyone know what "colored fire projectors" are? Do you fire them out of a mortar or just in an open cup? Seems like the yellow/orange burn of the NC's gonna wash out the colors--but I'm trying to keep an open mine (sorry, MIND).
nater Posted April 3, 2011 Posted April 3, 2011 I am planning on testing some with Strontium Nitrate and Green Dot fired out of mortars in a couple of weeks. It is my understanding that you can load a mortar and ignite it on top with an ematch. I am also planning on trying some in a small bucket or big tin can like you would a cremora.
shagaKahn Posted April 3, 2011 Author Posted April 3, 2011 Excellent. As all the NC I have is pelletized and all my Ba and Sr salts are much finer I'm wondering about the mix. Perhaps it ain't critical that all the grains are uniform. Please post us your results. Can't wait to try this.
Mumbles Posted April 3, 2011 Posted April 3, 2011 The ones I've seen were made on the disk type smokeless powders, typical for shotgun shells I do believe. Green dot probably is a good start. Typically they are made in loosely capped cardboard tubes. The tube dimensions reflect the flame you get. Narrow and tall gives that sort of flame. Short and fat, you get the idea. There is a lot of helpful information in Best of AFN 5 on pp 148-153.
Arthur Posted April 3, 2011 Posted April 3, 2011 AfIK shotgun powder in card pots lit from the top is the basic construction. Damp the powder with either Sr or Ba chloride dissolved in alcohol and when it's dry an ig will fire the device on cue. Blue doesn't work properly! 50g is very small, 150g is very large
shagaKahn Posted April 5, 2011 Author Posted April 5, 2011 Great reference; thanx Mumz. > There is a lot of helpful information in Best of AFN 5 on pp 148-153. Notice everyone mentions Green Dot; is this a fast (pistol) powder or slow (rifle) powder? Thanx,s
