Hi Edna,

I do a lot of pig tissues and have been successful with Mayers hemo
for years.  It is like wine..gets better with age.  Of course there is a
limit.  I stain for 20 minutes max, but have gotten away with less with a
20 min wash with tap water.  Eosin over-stains easily so I dilute it and
give just a couple or 4 dips.

I used to prepare pig skin for burn treatments.  What are you using if
for?  The powder project?  Sounds interesting.

Hope Mayers works for you.
