Solar Wax Melter
Here is a beautifully simple solar wax melter which Paul Magnuson of Pretoria, South Africa devised.
Melters made according to these plans work well. If the paper towel hangs over the side of the container, wax will sometimes wick off and drop to the bottom of the chest. This really is no problem, for the wax can be lifted off the bottom when cooled. You may use metal coffee cans rather than a plastic tub. That's the beauty of beekeeping and its associated activities: There are so many different ways of doing the same thing.
