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.

OK, I can't answer all of your questions. However no Magnesium carbonate will not affect colour saturation or binding properties of any resins/starches.


A much better anti caking agent more often used in pyrotechnics is cab-o-sil which is added at about 0.5% and this does not affect any properties of the composition.

Phew that was close.
