Hello all,

 I am studying for my HTL and have a question that has been a problem for me and was wondering if anyione out there can help. "What cuases paraffin blocks to crack ?" So far i have come up with it has to do the crystal formation during cooling, and I have seen some Histonet articles that say the block cooling plate at the embedding may be too cold ( less than -5 C). Can anyone confirm that is the is the correct cause of the problem?
