Anita,

 

     What kinds of tissue cut poorly?  Is it mostly harder stuff, like uterus or prostate?? And what exactly do you mean by "uneven sections"?  Does that mean thick and thin, or venetian blind effect? Also, what kind of blades are you using?  Is there adequate parrafin in the blocks??  I myself am notorious for having the minimal amount, and every once in a while I will have to re-embed something I haven't filled enough.  And what exactly do you mean by  uneven staining ?
