RE: Grocott problems

From:"Weems, Joyce"

1st of all - is your glass ware acid cleaned? 2nd - Do you have a neighbor
that you could ask to do parallel stains - just to see if it might be
something in the processing? If the same thing happens at your neighbor's,
then you'll know it's not just the stain.  Just my first thoughts.

	We have been experiencing problems with our GMS stain over the past
	weeks.  We run both a control slide containing fungal hyphae, and p.
	to cover our bases.  Our problem is: it is taking much longer to
stain in
	silver, and after we tone, and Na thio the slides, they are so pale
(or non
	existent), that they are unacceptable.

	We have made new: 5% silver, 3% methenamine, 5% borax, stock silver
	methenamine, 5% chromic acid, 0.1% gold chloride, and 2% sodium
thio.  All
	to little avail other than to be able to make them acceptable to
sent out,
	but not up to our usual standard.

	Any help on this very frustrating dilemma would be greatly

	Thanks in advance!
