Does Strontium Chloride give colours better than Strontium Carbonate? It would be easy and cheap to make. Would the Chlorine molecule contribute anything to the reaction?

It is harder to work with, quite hygroscopic, worse than strontium nitrate.

Not sure about the colour, the Strontium's red lines are probably more orange than the Strontium Chloride molecular lines. You could easily compensate with a chlorine donor and avoid the problems drying the stars. I generally find there is enough chlorine in there from the oxidiser in my reds, but a pinch of parlon helps.

I had some problems with sodium contamination from the meal priming once, the potassium nitrate was significantly contaminated. The stars burnt red unprimed, but once primed (while still moist) they would burn a pinkish colour.
