That's kind of the idea.
Flux is about adding a carbon element to the alloy/lead,, carbon molecules are lighter then the rest of the lead matrix, any impurities attach to the carbon because it's easier then staying in suspension with the lead,, it floats.
Any element that oxidizes/burns at lead melt temps will add the carbon you want,, waxes react quickly and "flame" is a rapid change to carbon.
Any wax will do, old crayons, candle wax, canning wax, Bees wax,,,
Drop a piece about the size of a pea and stir, there will be smoke and sometimes momentary flame,, then skim.
I use a tablespoon tied to a stick to skim/dross my lead.
