The present results confirm that there are four regions observed in the microstructure of as- cast 935 sterling silver alloys: Ag-rich matrix (α- phase), dendrite arms as a Ag-Cu solid solution, lamellar eutectic structure and degenerated eutectic copper. It can be concluded that the different in casting method, investment and metal mould casting, influence to the chemistry of the alloy and micropore but no significantly influence on cooling behavior and microstructure.
