R&R ADVANTAGE investment was developed for use in casting costume jewelry and silver, brass and bronze alloys. This product offers casters the product consistency and stability for which all Ransom & Randolph products are known. When compared to castings made with other low-cost investments, castings made with R&R ADVANTAGE material show a reduction of excess metal and water marking defects. These attributes, coupled with R&R?s unmatched history of consistency, make this an excellent choice for many casters. |
