Holama 14 lb 400 Mesh Oil-Free Casting Sand with Bentonite & Release Powder

For Experienced Users: Designed for skilled artisans, this casting sand comes with separately packed sodium bentonite and black mold release additive, allowing users to adjust the formula based on different casting needs. By controlling the amount of binder, release aid, and water added, you can fine-tune mold strength, release performance, and working consistency for safer and more successful casting results.

• Custom-Mix Sand Casting System | Includes 14 lb of oil-free 400 mesh casting sand with separately packed sodium bentonite binder and black mold release powder. Measure and mix with water to adjust bond strength, mold firmness, working consistency, and pattern release for different casting needs.
• Built for Experienced Casters | This is not a ready-to-use premixed sand. It is designed for users who understand sand casting preparation, moisture control, ramming pressure, venting, and safe metal pouring. Proper mixing and drying control are important to reduce steam-related casting risks.
• Fine Detail for Jewelry and Replicas | The ultra-fine 400 mesh sand helps capture small textures, edges, lettering, and delicate surface details when properly prepared. Suitable for rings, pendants, coins, medallions, miniatures, decorative parts, prototypes, and detailed replica work.
• Separate Binder and Release Powder | Sodium bentonite can be added as needed to improve green strength and mold integrity, while the black mold release powder helps reduce sticking between the pattern and sand. Separate packaging gives users better control than fixed-ratio premixed systems.
• Compatible with Multiple Casting Metals | Designed for sand casting projects using gold, silver, pewter, aluminum, zinc, copper, brass, bronze, and similar metals. Reusable and adjustable, this system is a practical choice for jewelry makers, hobby foundries, workshops, schools, and skilled DIY casters.
