RiderX Posted July 25, 2017 Posted July 25, 2017 (edited) is this possible? i haven't been able to find a single thing on using red gum bp for rice hulls for burst or lift charges i assume there's a reason that water/dextrin isn't used for unball milled powder and the alcohol is Edited July 25, 2017 by RiderX
OldMarine Posted July 26, 2017 Posted July 26, 2017 You could try dampening the hulls with alcohol and tumbling the powder in but I don't see that working too well. Why are you using red gum BP rather than dextrin bound?

OldMarine Posted July 26, 2017 Posted July 26, 2017 I've never made red gum powder. Are you using the CIA method?
RiderX Posted July 26, 2017 Author Posted July 26, 2017 I've never made red gum powder. Are you using the CIA method? No im not.I am doing it with a coffee grinder and 100 mesh screen. I am using these directions from skylighter http://www.skylighter.com/fireworks/how-to-make/Red-Gum-BP-short.asp
RiderX Posted July 26, 2017 Author Posted July 26, 2017 i found a place that sells 325 mesh potassium nitrate its a bit more expensive but i think im going to start buying it grinding and dbl checking it with the 100 mesh screen takes forever
PeteyPyro Posted July 26, 2017 Posted July 26, 2017 The alcohol/red gum method produces hard durable grains very quickly, since the alcohol evaporates off quickly. It may, however, be difficult to keep the rice hulls damp with the red gum/alcohol solution, without them becoming a gooey mess. Are you planning on misting the hulls with only the alcohol (keeping the red gum powder in the screened bp mixture), or use the red gum disolved in the alcohol?

RiderX Posted July 26, 2017 Author Posted July 26, 2017 (edited) what do u guy think about this potasium nitrate http://www.highqualitychems.com/5-lb-potassium-nitrate-325-mesh-w-anti-cake/ it has anticake in it would it still work for bp? would it work better being 325 mesh instead of the basically 100 mesh that i do with the screened method Edited July 26, 2017 by RiderX
OldMarine Posted July 26, 2017 Posted July 26, 2017 (edited) Try some from Phil. It's tech grade milled to a very fine mesh.http://ihaveadotcom.com/cart/index.php?main_page=product_info&cPath=72_119&products_id=571 With this and some quality airfloat charcoal you should be able to make a decent screen mixed powder and use Dextrin to bind it to your hulls.

Hardly noticable at all. Higher mesh is always better. The smaller particles your chemicals are, the better it can be mixed and the better it will burn.I have done both the CIA-method, screen-mixing ballmilled chemicals and ballmilling everything together. And there is no doubt; ballmilling is so much better.

OldMarine Posted July 26, 2017 Posted July 26, 2017 (edited) Here's some Paulownia airfloat that would work great.https://fireworkscookbook.com/shop/charcoal-paulownia-airfloat/ Using that KNO3 and this charcoal along with Dextrin and sulfur which are already very fine should result in a better BP than what you are currently getting. Using water rather than alcohol should help get the KNO3 spread throughout the mix as well. Edited July 26, 2017 by OldMarine 1

OldMarine Posted August 14, 2017 Posted August 14, 2017 Firebob on FW is actually the guy who processes the Paulownia. I'll find out when/if he'll be cooking/grinding again. 1

OldMarine Posted August 14, 2017 Posted August 14, 2017 (edited) I buy it 10lbs at a time do I don't run out in the off season! Edit: Sent a message to Chris at Fireworks Cookbook and he says he'll try to have some in by next week. Edited August 14, 2017 by OldMarine

Edit: Sent a message to Chris at Fireworks Cookbook and he says he'll try to have some in by next week.im not out yet i still have 3lb's from skylighter but i have some extra cash so i figured id pick up the better charcoal and some 325 mes potasium nitrate to make better bp with and save the stuff i got from skylighter to use for stars
OldMarine Posted August 14, 2017 Posted August 14, 2017 If he doesn't come through soon let me know and I can probably put a care package of Paulownia and some Red Stem Willow together for you. I love both of those charcoals. 1
rogeryermaw Posted August 15, 2017 Posted August 15, 2017 Just a quick tip. If you use the dextrin liquor method (dex dissolved in water) make what you need and don't store it long. It spoils and my gawd it stinks. Bout like sour milk. Didn't even try to save the spray bottle it was in..... That said, the stuff does work. I've used it to bind prime on various rubber and n.c. bound stars with excellent results. 2

For some, this is not an issue and saves them money, for others, the time/equipment/mess is not worth the cost savings.
