Material Classes: Authentic Clay vs. Metal Composite

True Compression-Molded Clay (Paulson / GPI): The authentic casino standard. Made from a proprietary clay-composite polymer blend compressed under high heat and pressure. Weighs 9.5 to 10.5 grams, produces a soft acoustic 'clack' (not a metallic clink), and stacks securely due to a subtle textured surface.
Ceramic: Smooth porcelain-like composite (10g) allowing full edge-to-edge sublimation printing.
ABS Composite with Metal Core (11.5g–13.5g): Common home dice-chip sets. Injection-molded plastic containing a metal washer slug to artificially simulate weight. Prone to sliding when stacked.
