Application Karat 18K Color 3N Yellow Application C, C/S Special Low melt loss, Less porosity Lower price Composition 34%Ag Color karat L * a * b * 18K 3N 88.34 4.88 Characteristics Density [g/cm^3] Hardness [HV] Melting range [ C] 18K 15.08 142 840-920 Casting temperature: Suggest temperature: 950-1060 C F lasks temperature: Suggest temperature: 500-700 C Help-solvent: Suggest using borax as help-solvent, for casting by machine dont need it. Set down casting temperature according to the identity of product, lower flasks temperature for layer product; higher flasks temperature for lighter product. Suggest advance-melting before casting, and make sure melting well-proportioned. Water Cooling Cooling in the air for 15-20 minutes before water cooling, more cooling time in the air for the layer product. Cleaning Using high pressure water to cleaning the plaster, and than put the product into 5-10% hydrofluoric acid in order to cleaning the residual plaster. Backup C=Casting C/S=Casting with stones
