Ransom & Randolph Ultra-Vest Investment-44 Lb Box

Ransom & Randolph Ultra-Vest Investment is a professional-grade casting investment formulated for use with gold, silver, and other alloys with casting temperatures at or below 2,200°F (1,204°C). Ultra-Vest is known for producing exceptionally smooth surface finishes on cast pieces, making it a reliable choice for fine jewelry casting applications.

Ultra-Vest is considered more process-friendly than some competing investments — it is not as instruction-critical as alternatives like Kerr Satin Cast, which makes it easier to work with across varying studio conditions. That said, following the manufacturer's mixing instructions consistently will yield the best, most repeatable results. Ransom & Randolph investments are engineered to deliver consistent performance from batch to batch, reducing variables in production casting workflows.
