pyrogeorge Posted February 23, 2012 Posted February 23, 2012 Potassium Perchlorate 45 Magnesium, atomized, 100-325 mesh 30 Cryolite 13 Polyvinyl Chloride (PVC). 10 Charcoal Airfloat 2 Has anyone make this composition?I plan to make stars but i didn't find any videos for these stars.Are bright enough or not?Thanks
Potassiumchlorate Posted February 23, 2012 Posted February 23, 2012 30% Mg should be pretty bright. I haven't made these but all his others Mg stars. They are very intense in light.

Potassiumchlorate Posted February 23, 2012 Posted February 23, 2012 A bit off topic: is there any rule of thumb how fine the MgAl should be in relation to the pure Mg? I have used 250 mesh MgAl with good results for Electric Magenta.

Sabdacrab Posted February 24, 2012 Posted February 24, 2012 Why?I think mg will be brighter than mgnal. Mg works great, It's just with Mg's incompatibilities it's safer to use mgal for most. (Me included!)
pyrogeorge Posted February 24, 2012 Author Posted February 24, 2012 I have already coated Mg with linseed oil.I think it will safe.

Potassiumchlorate Posted February 24, 2012 Posted February 24, 2012 If you like yellow, I think that is a good composition. Even organic compositions with just potassium perchlorate, cryolite and red gum are very intense in light. This has 30% Mg, and yellow can't be destroyed by high temperatures.
pyrogeorge Posted February 24, 2012 Author Posted February 24, 2012 (edited) I don't know if it rolled easy or i must make cut stars.Also,which prime needed? Edited February 24, 2012 by pyrogeorge
Potassiumchlorate Posted February 25, 2012 Posted February 25, 2012 I think they are better pumped. Best would be to use parlon instead of PVC, dissolve it in acetone and then pump them. I have pumped Blesers Red Mg, and that worked fine.

I second that I have always pumped them easyy on the magnalium it will wash out the color its a fine line,when I see a comp calls for magnesium alone I try magnalium and so far get great results.
pyrogeorge Posted February 25, 2012 Author Posted February 25, 2012 I found some usefull information about this composition.I read round stars ans shells book by David Bleser and has this composition. Need hot primeShould roll very round with acetone binder

Need hot primeShould roll very round with acetone binder Yes, its possible to roll them, though it takes some time, as I have mentioned before. I use this prime on Bleser's Mg stars: Potassium perchlorate 70Red gum 20Silicon 10
pyrogeorge Posted February 25, 2012 Author Posted February 25, 2012 I will try in my new star roller..In next few days will be done
Potassiumchlorate Posted February 26, 2012 Posted February 26, 2012 Just be careful, so that the acetone fumes don't come in contact with the motor. You'd better do it outdoors.
pyrogeorge Posted March 3, 2012 Author Posted March 3, 2012 Thanks for the info Patassiumchorate.Here is my star roller desing.Need only the container for the stars.http://www.amateurpyro.com/forums/topic/126-star-roller/page__st__20
pyrogeorge Posted March 5, 2012 Author Posted March 5, 2012 Yes, its possible to roll them, though it takes some time, as I have mentioned before. I use this prime on Bleser's Mg stars: Potassium perchlorate 70Red gum 20Silicon 10I haven't got silicon..can i use something else?
Potassiumchlorate Posted March 29, 2012 Posted March 29, 2012 Sorry for not replying for a long time. MgAl or Al would do fine. Al should be German Black/Dark or very fine bright flake.
pyrogeorge Posted March 29, 2012 Author Posted March 29, 2012 Thanks but i primed it with hot prime.I will make star gun test in few days.
