R&R ADVANTAGE® Investment is gypsum bonded investment powder excellent for casting lesser karat gold, silver, brass and bronze. Offers the jewelry caster the same consistency and product stability for which all Ransom & Randolph products are known all over the world. Casters see a significant reduction in excess metal and water marking defects with Americast® versus other low-cost investments. When used for high karat gold casting, Americast® Investment is considered somewhat more process sensitive than Ultra-Vest® Investment.
Ransom and Randolph is unanimously recognized as the world leader in gypsum bonded investment powder for jewelry casting.
Weigh the investment powder and measure the mix water at a ratio of 38-40 parts water per 100 parts powder by weight (38-40 ml water per 100 g of investment). Deionized water is recommended.
