I poured some silver into a graphite ingot mold, from a fused silica heating dish. I glazed the dish prior with borax.
Some of the flux poured into the graphite mold with the silver.
How do I remove it? The graphite moulds are quite delicate. I remove flux from gold and silver bars by boiling in dilute sulfuric acid, not sure how the graphite mold will respond if I try that?
