yes I may just have too. Well by dissolving the DSM in the lye it seemed to dissolve better, BUT the few specks that still showed up are zapping me. eeek no good. The few specks must have really soaked up the Lye and are now lye heavy. Like Homer Simpson says "DOO" I do still like the idea of also using the spice grinder stone bowl and stick to grind the DSM up a little finer, so I will continue to do that, plus use more to try and achieve a darker color. But result back in disolving it in with the hot oils. I noticed on soap I found on the web, they all advertise Black Dead Sea Mud and mine is more of a light tan color, so I am not sure if it’s even the same type of mud. End experiment
