Flux

[Rcmaveric]

I use my discarded tumble media and candle wax. Figured waste not want not and it all turns to carbon... Thought of possible contamination from the media, but it did not affect anything and works like a charm.

I mostly use pine pet bedding and candle wax for smelting and bee's wax in the casting pot.

I use marvelous and beeswax,any other suggestions.

I use those also....along with some cedar wood pencil shavings (from the pencil sharpener) , I find all three do a better job than just one flux product.
