Ransom & Randolph Ultra-Vest Investment-44 Lb Box

Ransom & Randolph Ultra-Vest is an excellent investment for casting in gold, silver and other alloys that can cast at 2,200F (1204C) or below. R&R Ultra-Vest produces a very smooth surface.  It is easy to use and not as instruction critical as Kerr Satin Cast, making it process-friendly, although for the best repeatable results you should always follow mixing instructions.  R&R investments provide consistent results from batch to batch.  Sold in a 44 lb (20 Kilos) cardboard box.
