silver melts | Gold Refining & Metal Extraction Forum

As a rule, use only enough carbonate to get a fluid slag (you might try 1 part borax to 0.5 parts carbonate, thoroughly mixing it into the crude silver powder). We typically pour cones first, de-slag, XRF the slag and mill it if it shows values and re-smelt with a thinning flux. 99% of the time we get that right the first time.
