[Histonet] Sectioning Probems, again

For all those who wondered how I embedded my mouse hearts that won't section-

The processing schedule is as follows:

Tissue samples hold in 70% alcohol until the process begins using an Autotechnicon.  If you don't know what that is, ask someone who has been doing histology for a loooong time.
80%, two 95's, 3 100's, 3 Citrisolve all for 1 hour with agitation.  2 changes of Surgipath EM-400 (same as I've used in clinical labs).  Then 30 minutes to one hour in EM-400 under vacuum.

Since I inherited all the reagents and embedding paraffins's and I have to get the histology core running with minimal expense (I know, I know, but tell that to the CEO) I must work with the reagents I have.

I can tel you that liver samples were embedded using the same reagents and wax and they sectioned fine.  Well, fine for liver.

Thanks for any input you can give.
