	What is the hardest paraffin on the market?  I've found Gold Standard
	Peel-A-Way with a melting point of 62-64 degrees C.  Does anyone have
	any comments about the Gold Standard paraffins?  Years ago, a lab used
	some sort of additive to their paraffin for bone that made the block
	yellow in color.  Does anyone know what that could have been.  I believe
	it was something like picrotin?  Ring any bells?  Thanks, Sarah
