"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? _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
