Hematoxylin crystals haven't been on the market for years.  The powder works
fine for Ehrlich's and for every other variant that I've tried (about 20).
If you put the powder and the ethanol into a small flask with a magnetic
stirring bug and let it stir for a while, all of a good quality powder will
dissolve.
