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

[Potassiumchlorate]

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.

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]

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

[pyrogeorge]

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

[Potassiumchlorate]

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

[pyrogeorge]

Thanks for the info Patassiumchorate.
Here is my star roller desing.Need only the container for the stars.

I haven't got silicon..can i use something else?

[Potassiumchlorate]

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.
