[Histonet] Black paraffin and cassettes

[Jo Dee Fish]

Dear Steven,
Here is what I have learned to do for aorta pinouts:
Melt about half a pound of pink dental wax along with about 1/4 piece 
of black candle dye.  I'm sorry, there is no weight on the package, 
so it is actually a piece about the size of my thumbnail.   Just mix 
and stir until it is a color you would like.  I use a small cardboard 
box, with no seams, to mold the "plate" of wax.  It comes out easily 
after chilling (I use one of my cold plates to chill them).  The 
cassettes are too small for what we are pinning out.
I hope this helps, and good luck!
Jo Dee
