Question: Magnesium Carbonate as anti-caking agent?

19 October 2016 - 04:35 PM

I have some questions about MAGNESIUM CARBONATE:

 

1.) How much "Magnesium Carbonate" should I add to KNO3, KClO3, BaClO3to make them free flowing and to reduce caking?

 

2.) Does the "Magnesium Carbonate" reduce the color purity of BLUE and GREEN STARS?

 

3.) Does the "Magnesium Carbonate" reduce the adhesive force of PHENOIC or RICE STARCH?

 

4.) Is "Magnesium Carbonate" compatible with all compositions?

 

I hope someone can answer all or some of my questions.


What is the ideal size for colored star in 1,2-inch (30 mm) cylinder shells?

05 September 2014 - 12:29 PM

Hi,

What is the ideal size for colored star in 1,2-inch (30 mm) cylinder shells?

The burst look sparse and the stars will burn too long, when using 1/4-inch colored stars pressed with Wolter Pyro's star board. Only 25 to 30 pieces of 1/4" stars go in a 1,2-inch shell !

I hand press my COLORED STARS using a STAR BOARD. I use barium chlorate and potassium chlorate for my stars, because potassium perchlorate stars burn to slowly.

QUESTION: So, what will be the ideal size?  3⁄16" (4.8 mm) or even smaller 9⁄64 (3.6 mm) ?
