Ransom & Randolph recognized the need to provide the European jewelry caster with locally sourced jewelry investments. As a result, R&R’s American research & development team developed formulas using primarily European-sourced raw materials. 

R&R^® Argentum^TM investment was formulated for casting silver, brass and bronze alloys. Casters report excellent casting results using R&R ARGENTUM investment.

These formulas are manufactured to R&R’s demanding quality standards at Dentsply facilities in France and Germany.
