Certus Prestige™ POWERCAST Investment Powder for Figurines and Sculptures (49 lb Sack)

Certus Prestige™ POWERCAST Investment Powder (49 lb Sack)

The Professional’s Choice for High-Value Gold & Silver Sculpture

When you are casting a statue in pure .999 silver or 24k gold, the stakes are incredibly high. You need an investment powder that captures every nuance of your original sculpture while possessing the structural integrity to handle heavy, dense pours without cracking.

Certus Prestige™ POWERCAST is engineered to bridge the gap between fine jewelry precision and industrial strength. Designed specifically for non-ferrous metals, this gypsum-bonded investment offers the perfect balance of permeability and strength, ensuring that gases escape efficiently during the pour—vital for avoiding porosity in larger, solid statue castings.

Whether you are casting devotional figures, limited-edition art toys, or museum-quality reproductions, POWERCAST delivers a "skin-quality" surface finish that drastically reduces polishing time—saving you precious metal dust and labor.

Why It’s Perfect for Precious Metal Statues:

• Flawless Surface Reproduction: Formulated to replicate the finest textures of your original wax or resin model, ensuring your artistic vision remains intact in metal.

• Reduced Finishing Loss: Achieves a satiny-smooth surface right out of the mold. Less grinding and polishing means you keep more of your expensive pure gold and silver weight in the finished piece.

• Structural Reliability: High-purity refractory ingredients provide superior mold strength, preventing "blowouts" or finning even when casting heavy, solid figures.

• Zero-Defect Formulation: Proprietary control additives actively fight surface defects and watermarks, ensuring a clean, gallery-ready appearance.

• Versatile Casting: Safe for use with all non-ferrous metals with a melting point up to 2,200°F (1,204°C), covering all silver and gold purity levels.

Optimized Mixing for Large Flasks:

• Mix Ratio: 34 – 35 parts water to 100 parts powder (by weight).

• Mechanical Mix: 3 ½ – 4 minutes.

• Vacuum: De-air the slurry until it boils vigorously (1 – 1.5 mins), pour down the side of the flask, then vacuum again until the filled flask boils (1 – 1.5 mins).

• Critical Step for Statues: Allow flasks to bench set undisturbed for 2 full hours before burnout to ensure maximum mold hardness.

Protect your investment in pure metal. Don't risk your masterpiece with generic powders. Add Certus Prestige™ POWERCAST to your cart and pour your next statue with absolute confidence..
