Merlin Posted August 15, 2015 Posted August 15, 2015 I have quite a supply of bright aluminum on hand I got at a discount on skylighter. The attach pic is somewhat misleading. It is supposedly good for a slow nitrate flash booster on rice hulls. The stuff clumps and SMEARS and is quite difficult to diaper mix. It is not a powder but a coated flake aluminum. Has anyone ever used this for anything or would it be best to use dark aluminum for nitrate booster on rice hulls?
pyrokid Posted August 15, 2015 Posted August 15, 2015 I have some of the shiny, extremely messy, and dusty bright flake aluminum, though I didn't get it from Skylighter, and it works in perchlorate flash. I will say that reports made with this bright stuff are not as loud and give a brighter flash than those made with dark aluminum. This bright flash could be quite a distraction in color shells.
Merlin Posted August 15, 2015 Author Posted August 15, 2015 Your right. Do you think nitrate,dark AL and sulfur would make the best Booster to dust on BP coated rice hulls for 4 and 5 inch shells or would it be best to use a central flash bag of 70/30?
OblivionFall Posted August 16, 2015 Posted August 16, 2015 KNO3:Al:S is more friction sensitive than KClO4:Al so I would go with KClO4:Al or if you can Perchlorate TPA Flash
schroedinger Posted August 16, 2015 Posted August 16, 2015 (edited) Oblivion do you have any experience with different boosters? The question if you use a central flashbag mostly depends on the overall construction. They are mostly used for plastic and sfera/spider type brakes. If you only want to enhance a normal working burst, dusting is all good. For this normally slow flash is used. You can either just drop some onto your hulls afer filling the hemi or tumvle your hulls with 2%. You can also boost your shells with benzolift made with hot bp or straight whistle, these don't give a white flash. Edited August 16, 2015 by schroedinger
mabuse00 Posted August 16, 2015 Posted August 16, 2015 Concerning the bright flake stuff: Has anybody here ever tried to get rid of the wax?Washing in gasoline ect.? This would give an almost non oxidised aluminium powder. As long as it's not stored forever and kept dry, it might offer a much better performance in flash. Has anyone ever used this for anythingFlash. I found it unsuitable for stars, because the wax impairs the binding.
Merlin Posted August 16, 2015 Author Posted August 16, 2015 For dusting BP rice hulls which slow flash is better? Nitrate aluminum sulfur or something like benzolift I wouldn't think 70/30 would be used for this. I do build plastic with central flash bags but also paper shells. Also I avoid chlorates completely. I am wanting to begin pattern shells.

Sparx88 Posted August 16, 2015 Posted August 16, 2015 For me when I used a nitrate alum sulfur booster it worked so well that I no longer waste perchlorate with boosting anymore. 2 to 3 grams at the center of the burst on all 3 in. Normally using paulownia bp is good on its own but squeezing out a bit more kick is nice though
