Question: Magnesium Carbonate as anti-caking agent?

[Peter8]

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.
