I'm a little leery of Greenlight Stump Remover as a source of KNO3. I 
started out with a 500g bottle of ACS grade KNO3 from the local 
university's chemical stockroom. The laboratory KNO3 was pretty much 
white like rock salt. When dissolved in water, the solution was 
completely clear with no precipitate. Greenlight Stump Remover is not 
white, and when dissolved in water it is very cloudy with this 
gelatinous stuff floating around. What's all that extra junk?
