Prestige ORO Gold & Precious Metal Casting Investment Powder

Achieve flawless, museum-quality casts with Prestige ORO Investment Powder. Developed specifically for high-end jewelry manufacturers, Prestige ORO is an advanced refractory ceramic formula engineered to handle the thermal demands of high-carat gold (18K and above), white gold, palladium, and fine silver. If your workshop handles dense patterns, heavy casting trees, or highly intricate details that cannot afford a single surface defect, ORO is your gold standard.

Available in flexible packaging sizes to support both boutique studios and heavy-volume industrial production: a high-efficiency 49lb bag, a highly protected 50lb plastic drum, and a high-capacity 100lb bulk drum.

The Prestige ORO Advantage

• Zero-Defect Surface Quality: Formulated with ultra-fine, graded un-ground silica particles that replicate the microscopic details of your master pattern without water marks or flashing.
• High Thermal Stability: Specifically engineered to resist expansion and cracking under aggressive high-heat burnout cycles, protecting fragile prongs and channels.
• Heavy Tree Support: Possesses superior green strength and fired strength to prevent mold erosion or collapse when casting large quantities or heavy, dense gold trees.
• Effortless De-vesting: Quenches smoothly and breaks away cleanly, minimizing the time spent pickling or mechanically cleaning delicate details.
• Extra-Smooth Creamy Pour: Easily mixes to a dense, ultra-fluid slurry that releases trapped air bubbles effortlessly during vacuuming.

Technical Specifications & Mixing Parameters

• Target Alloys: Yellow Gold (10K - 24K), White Gold, Rose Gold, Fine Silver, Sterling Silver, and Brass/Bronze.
• Water-to-Powder Ratio: 38 to 40 parts water to 100 parts powder by weight (Adjust slightly based on detail complexity).
• Working Time: 8.5 – 9.5 minutes from the initial pour.
• Slurry Temperature: For best results, keep water and powder between 70°F–75°F (21°C–24°C).

Safety & Storage Note: Always wear an approved respirator or dust mask when mixing investment powders to avoid inhaling crystalline silica. Keep drums tightly sealed between uses; the 50lb and 100lb plastic drums feature locking rings that maximize protection against ambient humidity, ensuring a stable, predictable setting time for every batch.
