Sodium nitrate cheaper than Potassium nitrate? Hah! Where do you get your Nitrates from? Sodium costs about three times Potassium nitrate where I get it, and my supplier was not hard to find. As fars as hygrscopicity goes, My experience shows that a comp containing KN and Sucrose will become damp over time, while with Sodium nitrate you will get a puddle...
On another note, I too use Sodium nitrate "fairly" regularly for rich Yelllows and golds, though I must be ALOT more careful with the choice of fuels than with the Potassium salt if I do not want a pile of mush.
I pay ?7.50 for 9kg of 99% pure fertilizer grade nano3 or ?3.00 per 3kg,no I'm not gonna tell you where I get it I dont wanna give curious kids any ideas and my supply to be stopped,I'll ge as far as to say its a 5 min drive from where I live so no postal costs either
As by the hygroscopy issue all you need is some airtight tuppawear or a 5 gallon plastic bucket if your devices are large and the problems is gone,I think it a total none issue
The colour wavelength the sodium nitrate produces is 589nm right in the edge of orange in the spectrum,the addition of some lithium carbonate should push the flame deep into the orange part of the spectrum and the awsome light emmiting properties of sodium will give you really bright stars and fountains without any extra addition of expensive metal powders
