Sulphurstan Posted December 6, 2017 Share Posted December 6, 2017 Yus, amazing! Would you be so kind to share the composition, especially the third white one? Is it the one given by pirotek yesterday? Link to comment Share on other sites More sharing options...
Yus Posted December 6, 2017 Share Posted December 6, 2017 Ba(NO3)2 - 68%, AlMg - 26%, Bi2O3 - 3%, binder - 3%. 2 Link to comment Share on other sites More sharing options...

Ubehage Posted December 8, 2017 Share Posted December 8, 2017 (edited) #3 MgAl typically isn't coated with anything. For magnesium, linseed oil or dichromate should both work.Just be aware that dichromate is the closest thing you come to actual death while making pyro.It's carcinogenic as f***. Sorry! I didn't check the date before replying. Edited December 8, 2017 by Ubehage Link to comment Share on other sites More sharing options...
OldMarine Posted December 9, 2017 Share Posted December 9, 2017 Wear gloves, wash your hands and don't eat the orange powder. I actually keep an excess in distilled water and just use it for wetting comps that need it so I don't have to mess with a respirator while dealing with it. 3 Link to comment Share on other sites More sharing options...
Sulphurstan Posted December 10, 2017 Share Posted December 10, 2017 Ba(NO3)2 - 68%, AlMg - 26%, Bi2O3 - 3%, binder - 3%.I just tested a star on the ground, and it looks very promising!!! Will fill a rocket head with 5 mm cuts and hopefully enjoy this (for me) new composition. Thanx again Yus 😀😊 1 Link to comment Share on other sites More sharing options...
sumagg27 Posted December 12, 2017 Share Posted December 12, 2017 What is mesh size of mgal works good in this composition.Thanks Link to comment Share on other sites More sharing options...
MrB Posted December 12, 2017 Share Posted December 12, 2017 Wear gloves, wash your hands and don't eat the orange powder. That made me think of a friend who keeps saying "eat the yellow snow, it might be beer" for some reason.Sorry, quite off-topic. Link to comment Share on other sites More sharing options...

Sulphurstan Posted February 22, 2018 Share Posted February 22, 2018 Yus,In the bi2o3 strobe star system, do you think, we could make a blue one? Have you made some experimentation to get it blue?Mixing in copper compounds (copper benzo, cuo, cuco3...) Link to comment Share on other sites More sharing options...
