Magnetic stirrers have changed SWIM's life. Coupled with heating her naptha, yields have shot straight up for the variation of Norman's tek she uses. She uses a separatory funnel to keep all lye/mimosa mixture out of her naptha. She also always cleans with Sodium Carbonate. This last freeze precip. brought a much more yellow and powdery product. SWIM feels almost certain it's okay, just hope for some reassurance...
