When I wrote, "Greenlight has verified it's just KNO3," I meant that it 
doesn't contain additives.  I wasn't addressing impurities.  Later, I wrote 
that Green Light is *relatively* pure.  It wasn't my intent to imply that 
it is 100% pure.  I should have been more precise in my meaning.  If my 
words were misleading, I apologize.
