Priming chlorate stars

[hashashan]

Hi, Guys what priming composition you use for chlorate stars?

[DeAdFX]

In my experince chlorate stars don't need priming. What compisition are you using that would require a prime? Perhaps just a mix of chlorate, charcoal, organic material, bulls eye shellac might be sufficent?

Priming composition #6

Comments: This prime is safe to use with chlorate stars and gives a much better color than a black powder prime. The difference is most noticable on red stars which tend to a dark salmon color when primed with black powder.

Preparation: Dissolve the potassium nitrate in hot water and mix with the charcoal.

 

Potassium chlorate................................52

Potassium nitrate.................................8

Charcoal..........................................30

Lampblack.........................................10

Binder............................................+5%

 

 

I use charcoal (40 parts) as I have no lampblack and simply screen all ingredients together. Apparently lampblack should be avoided with chlorates anyway is it may contain sulfur,sulfates etc...
