• Complete Sand Casting Kit with Flask Frame | Includes 5 lb of oil-free 400 mesh red casting sand, separately packed sodium bentonite binder, and a cast iron flask mold frame. A practical starter system for users who want both molding material and a reusable frame for small metal casting projects.
• Custom-Mix Formula for Experienced Users | This is not a ready-to-use premixed oil sand. The separate bentonite binder and sand allow skilled users to adjust water level, bond strength, mold firmness, release performance, and working consistency based on project size, pattern shape, and casting method.
• Cast Iron Flask Mold Frame Included | The included flask mold frame helps hold and shape the sand mold during packing, pattern removal, venting, and pouring preparation. It is suitable for small jewelry, rings, coins, medallions, miniatures, decorative parts, and detailed replica casting work.
• Fine 400 Mesh Sand for Detail Reproduction | Ultra-fine 400 mesh sand helps capture small textures, edges, lettering, curves, and fine surface details when properly mixed and rammed. Ideal for users working on jewelry metal casting molds, small sculptures, custom prototypes, and hobby foundry projects.
• Works with Multiple Casting Metals | Designed for sand casting projects using silver, copper, brass, bronze, pewter, aluminum, zinc, gold, and similar metals. The adjustable oil-free sand system is reusable, flexible, and well suited for jewelry makers, metal casting hobbyists, workshops, and educational use.
