Jumped 10 per unit in price? Isnt there some 3rd world #### hole you can have them made where they can go back to reasonable prices? Im going to have to cut back on the quantity I wanted to buy now.
Just saw your post about potassium nitrate. Last time I checked it burns too hot for using dyes. So for white smoke it is a good cheap choice with a increased fire hazard but colored smoke will ave the dyes go from vaporizing to being destroyed therefore making them less bright if they even put off any color at all. Chlorate and lactose was the standard. Never seen a working color mix using nitrates so hope it works out for y'all and someone figured out how to get it to burn cool enough not to destroy the dye.
