In remarks about the solar melter Layne Westover mentions: “The leftover
slum gum, pollen and impurities/debris I throw into my compost bucket...”

Since solar wax melters are not overly efficient, a fair amount of wax is
retained by the slumgum. I remelt the slumgum in hot water. Then I pour
that through a fine mesh colander and press as much of the liquid as I can
out of it. The wax is darker and admittedly has a slight earthy aroma.
While not acceptable for cosmetic uses, it probably would be suitable for
the leather crafters Karen mentioned.
