Mix the powder into Part A first, then add Part B. Start conservative at roughly 1 g per 8 oz of resin and increase for stronger color or opacity. Layer with complementary micas for swirl and depth effects.Important: this is a casting pigment only — NOT for stabilizing resin or wood. Resin Type Starting Ratio (Powder : Resin) Notes for Maximum Color & Pearlescence Alumilite Urethane (Clear or Slow) 1:30 Grams : Grams Fast cure helps keep mica suspended — minimal sinking; great for translucent shimmer. Epoxy (JB Royal, Liquid Diamonds, etc.) 1:10 Grams : Liquid Ounces Start light for depth and sparkle; go heavier for opaque metallic coverage. Stir slowly to avoid bubbles. Polyester Resin 1:10 Grams : Liquid Ounces Strong color payoff; pressure pot recommended for bubble-free casts with even flake orientation. Pro Tip: the richest shimmer appears in clear resin with a moderate load, finished with a gloss polish.Project ideasUse this sapphire powder for swirl pen blanks, accent veins in river tables, or elegant jewelry pieces.
