I have had some success by placing the glass coplin jar in a beaker of
water and then heating all that up. I use this method for my myelin
stain where the cresyl violet needs to be at 68 degrees F and remain
there for the duration of staining. Now, I do this in a water bath, not
a microwave so I am not sure if the beaker will withstand it either but
it mat be worth a try.
