Solar Wax Extractor

I wanted to extract the wax from a hive that we removed from an old house. I read about some solar extractors on the net and thought this was a good idea. I made mine a little differently but with the same outcome. My wax extractor is simply an old fire extinguisher cabinet that you have seen in commercial buildings. They have the rounded plexiglas cover-excellent for solar heat collection. All I did was clean the cabinet up and painted the interior of the cabinet with a black paint. I also wrapped the cabinet with duct insulation for heat gain. I placed a foil pan that I perforated with a tiny nail inside another pan that is not perforated. I placed the wax on top of cheese cloth that is streatched over the perforated pan. It worked fine. I measured the temp inside the cabinet on a sunny day and it measured 138 deg. F
