[QUOTE="entoptics, post: 1890567, member: 104268"] I work with very precise instruments, measuring the chemistry of rocks. We have to take a fist sized rock, turn it into powder, then take an aliquot and mix it with a flux, eventually taking about an 1/8 teaspoon of powder for the final measurement. Mixing is our 2nd largest source of error (#1 is getting a homogeneous aliquot). An ex-student of mine now works for a paper coating company. His entire job is streamlining and improving their mixing processes. That said, I mix powder all the time, exactly as you mention, but I mix it VERY thoroughly. As in several minutes of turning, tumbling, shaking, rolling, etc. Be gentle enough not to pulverize anything, but be thorough. Tip end to end 20 times, then roll it over side to side 20 times, repeat. [/QUOTE]
