Re: Mr. Swisher: Paris Green Blues

Joel, I've used this formulation for blue cut stars over many years
(actually decades). It's usually credited to Weingart.

48 Potassium Chlorate
16 Barium Nitrate
18 Paris Green
3 Dextrin
10 Shellac

Sometimes I would also add a small percentals of fine aluminum for
brightness, but at the cost of detracting from the color saturation.
And do, I don't know the reason for the dextrin, but since it was in
the formulation given to me I've always used it.

Usually I used these stars in 3-break color and report shells.
When used in a mixed color shell, the blue was largely washed out by
the red and white stars.
