Interesting idea to lighten the wax.. Using the solar melter helps lighten the wax a bit as well.. but I just use the electric burner with the water in it.. bring it to boiling and start adding cappings.. I also use screen wire and cheese cloth. I pour it through the straining wire and cloth into a 5 gallon bucket and let it cool there.. when the cooled wax comes off the water/honey mix I scrape the bottom gunk off the cake of wax, and I may even run it through a t shirt after that if the wife wants wax for candles.. for rubbing my frames or to send in to the buyers the single straining is sufficient..
While the 5 gallon bucket cools, I heat more water in the pot. When boiling I run my cheese cloth and t shirt through that boiling water to clean the cooled wax from it, making it re usable..
The wax I pack up to sell I leave in the 5 gallon diameter size cakes. The wax I keep for my own, or my wifes use I re melt, re filter into an empty pot, and keep it warmed so I can pour it into muffin/cupcake pans.. this gives me a perfectly sized piece of wax to USE to rub frames etc.. OR, for my wife to melt down and make candles from...
