Thanks, Harald. Boric Acid did not cross-polarize, so I decided to explore the crystaline structure by feathering the darkfield stop on another scope.

Re: Sodium carbonate

Thanks. During the winter when the ponds are frozen, it's nice to have chemicals around. Often I air dry chemicals, but then I may put the slides on a gravy warmer to force the crystalization, which was the case with Sodium carbonate.
