I recently wondered if there was a way to test if the powder is properly milled before stopping the milling process. This was due to the “pearls” or specs of potassium left after testing the burn on some of my batches. I accidentally came upon the answer yesterday in the Waltham abbey book on page 83.
This ties into mitigating the clumping problems you can have in your mill and like Vettepilot proved, the importance of keeping your mill jar leveled. I noticed these specs before in some batches of the milled powder and not in others. Moisture levels will affect this so it should be tested dry not dampened. Sure beats pressing, grinding and screening for nothing. It’s a handy little Quality control check I will add to my process going forward.
