[Histonet] tissue swelling out of block

[Bartlett, Jeanine (CDC/CCID/NCZVED)]

Is he saying that he embeds processed tissue and removes the chilled
paraffin block from the base mold that it then swells up in the
paraffin?  Before it is trimmed and placed on ice?

Hi all,

a friend recently got a job in a veterinary histo and has some troubles
in cutting. He tells about paraffinblocks, where the tissue is swelling
out while warming like a small hill.  I referred to the possibilty of
taking up humidity that causes swelling. 

Do you know other causes for this problem?

 

Thanks in advance
