Mixing and combining
Before use, the aggregate materials are crushed down to various particle sizes. Particle
size impacts the aesthetic texture of the end‐product. Fine particles create a smooth quartz
surface; whereas, large particles create a surface with visible crystal structures.
Each end‐product has a unique formula that is pre‐programmed into the production
line. The automated system then extracts the raw materials from storage and transports them
