Ralwax1 was and is manufactured by Raymond A Lamb.  It is 
commonly available paraffin wax compounded with "high molecular 
weight plastic c-polymers, which impart toughness and fleibility to 
the wax".  It is the only histological wax I have found that has a 
noticeably different crystalline structure.
It can be particularly useful as a support medium for very hard 
and/or tough tissue.  It is not a panacea for cutting bone, fibrous 
uterii and other swear-word inducing tissues.  A sharp blade is still 
the prime requirement.  But Ralwax IS different.
Cannot remember their US agent at the moment, but it will come 
back to me (I hope to heaven it does!)
