Important Crafting Instructions HANDLE WITH CARE: While extremely scratch-resistant, ceramic is a rigid material. It can crack or shatter if dropped on a hard surface. AVOID OVER-EXPANDING: Do not use excessive force on a ring mandrel when sizing or working. Over-expansion can cause the ceramic to crack. Creative Applications Bentwood Rings: Use as a strong and stable interior for your handcrafted bentwood rings. The black ceramic provides a beautiful contrast to any species of wood. Carbon Fiber & Composite Rings: The ideal core for wrapping carbon fiber, fiberglass, or other composite materials to create lightweight, high-tech rings. Hybrid Designs: Combine with other materials, like creating a wood exterior with a crushed opal inlay that sits flush with the liner's edge, for a unique multi-material ring.
