Bob, Is your KNO3 in pelleted form or is it a powder? I ordered a 1 lb bag for $5.00, but it's in pelleted form. I grind it up in a deep cup but this is very laborious and time-consuming. I was thinking of using a peppercorn grinder unless you or anyone else has a better idea. What are the rest of you guys using? Powdered or Pelleted? Thanks, Andrew
