A few years ago I built a solar wax melter.  It was cobbled together from stuff laying around or given to me.  It seemed like an interesting  thing to experiment with!
 
I have learned that you should not use styrofoam insulation, as it tends to melt.  The semi-ridgid fiberglass stuff that heating and airconditioning people use to make ductwork with workes well,  and sometimes they will give you scraps.
 
I also found that the piece of aluminium I used for the metal lining was a bit of good fortune.  It was something called 'stucco' and has a 'pebbled' surface.  At just the right angle (sorry, have not measured that angle!) the trash stays and the wax flowes out.  Well, mostly.
 
Hope this gives you folks some ideas!  Happy melting!
