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

30% Mg should be pretty bright. I haven't made these but all his others Mg stars. They are very intense in light.

sub the magnesium for 325 mesh magnalium youll like it

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.

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!)

I have already coated Mg with linseed oil.

I think it will safe.

Okay, cool!

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. :)

I don't know if it rolled easy or i must make cut stars.

Also,which prime needed?

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.

I found some usefull information about this composition.

I read round stars ans shells book by David Bleser and has this composition.

  • Need hot prime

  • Should 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 70

Red gum 20

Silicon 10

I will try in my new star roller..In next few days will be done ;)

Just be careful, so that the acetone fumes don't come in contact with the motor. You'd better do it outdoors.

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.

Thanks but i primed it with hot prime.

I will make star gun test in few days. ;)
