[Histonet] Plastic sections

[Wurdak, Elizabeth]

Hello Histonetters,
We are having trouble with the JB-4 embedding medium.  No matter how
carefully we follow instructors provided by the vendor, EMS, our blocks turn
out to be too hard to section with sharp glass knives.  Should we cut back
on the catalyst, soak the blocks or switch to a different embedding medium
altogether?
Any help you can give me will be much appreciated.
Liz
