[Histonet] Black paraffin and cassettes

[Monfils, Paul]

Steven,

If the block doesn't have to be processed and sectioned, the paraffin could
easily be colored by stirring in powdered carbon, which is essentially the
same colorant found in black drawing ink. And the cassettes could be colored
with one of the new spray paints designed specifically for painting
plastics.
