Thank you for the clarification. I have seen this GRIT in some of my own emulsions. I have tried to filter out the grit with multiple gold mesh filtrations. But the subsequent emulsion still "sucked". I think that I will switch from magnetic stirring plates to overhead mixers, with hot-plate heated water baths under the emulsion. Buying used magnetic stirrers on Ebay is a real crapshoot. They often just do not have enough torque.
