What is the difference between Corian® and quartz?

Quartz is a mineral material in coloured granules held together by acrylic or polyester resins. It is rigid, heavy, impossible to repair or restore. Joints are always visible.
Corian®, instead, is a compact material, held together by acrylic resins. It is simultaneously flexible and rigid, allows for invisible joints and can be repaired if damaged. The number of possible joints is almost infinite.
