Electric kilns realy aren't too good an idea for wax burnout.

The elements acquire an oxide coating in normal use which prevents or at least slows down further oxidation. Burn out of wax is a reducing operation and this will remove the oxide layer and the elements will have a very short life. Check out the ceramics books and you will find this restriction on attempting reducion firing in these electric kilns.

A simple direct propane fired raku kiln is much better and not expensive to build. Punch up raku on your search engines and find out all you will need. Its best to melt out as much wax as possible over boiling water and eliminate a lot of smoke in the final burnout.
