Hi, I am looking for some guidance regarding melting scrap gold for re-use in a ring that I am constructing.
I have about 22g of 9ct yellow gold that I have melted down and will be rolling the ingots down into the various thickness's required for the ring construction. Will there be any issue in terms of assay quality of the final piece if I melt and re-melt the gold to get the various components. Should I be adding casting grain to the melt at any point to pull the gold back to 9ct assay quality.
The gold that I started with was all provided by my client and hallmarked as 9ct. Part of the design introduces a new component of white gold, the finished product therefore will have to be hall marked - hence my concern regarding maintainng assay quality of the yellow gold.
Kind Regards Jim
