Light, but no lightweight.

For Reiziger Expanded clay it all starts with meticulously clean clay mined from a natural geologic source that dates to ancient times. That’s the level of quality that goes into making every single ball of expanded clay. The extracted clay is then fired in rotary kilns at 1,200 °C (2,190 °F) causing it to pop, like popcorn, and become porous and lightweight yet even more durable – it’s 30 percent stronger than most clay and one fifth the density of concrete. The finished product has a bright orange colour with a uniform structure free of defects and harmful impurities 5. Attention to detail – it’s what we’re famed for.
