I just was experimenting with waxing my prints from the Alps printer, and 
I consulted a site with information on encaustic.  You might want to take 
a look at it.  http://www.sfo.com/~sinopia/encaustic.html
I ended up dissolving beeswax in turpentine.  Worked fine.  It must be 
horrible, but the smell still brings back strong image of being a young 
student in art school.
