The trick with celestine blue is the formula you use to prepare the staining solution.
Gray prefers (and I have also used years ago) one that is as follows:
water -- 100mL + ferric alum -- 2.5g + celestin blue B-- 0.5g + glycerol -- 14 mL + sulfuric acid -- 2 mL.
Boil the dye in the alum solution (prepared first). Cool, filter and add the rest.
Staining from 5 min to 1 hour (too long for a routine lab); will not overstain. Does not need "bluing".
I don't think the hematoxylin will be unavailable any time soon.
