[Histonet] Re: Histonet Digest, Vol 3, Issue 36

From:Amos Brooks

         I've never really had a problem with that. I've seen problems 
similar to those described, however they were always caused by someone 
doing something like not using a tamper while embedding the tissue or if a 
sponge was used instead of a tissue or tea bag for processing. If the 
tissue is properly treated there will be no problem. I've seen 5-7 pieces 
in a block with no tissue loss even on recuts. The trick is to be REALLY 
careful. Don't believe everythnig you read.
