Achieving Marble Veins and Terrazzo Chips in Plaster Casting

Pre-Casting Terrazzo Flakes: Pour thin color sheets (terracotta, slate, olive), let them dry completely, and hand-crush into multi-sized chips.

Folding Chips: Fold 20% volume of chips into fresh white plaster mix immediately before pouring to achieve crisp terrazzo patterns.

The Gentle Marble Technique: Drop concentrated pigment into your base cup, draw a single "S" curve with a mixing stick, and pour steadily without over-stirring.
