This is Haifa brand KNO3 that has been ball milled. It easily passes a 200 mesh screen and that's as small as I can test. Due to the fine granulation, (like powdered sugar) this readily clumps but will easily break apart with your fingers or a screen if kept dry .
This product is produced by Haifa under stringent specifications for applications where consistent quality is a priority. Standard grade and prilled KNO3 contain binders and other impurities.
This product can be shipped by UPS Ground to the lower 48 states only.
