Home » Cai Modeling Materials
These materials were developed as alternatives to traditional modeling materials. As such, they work best for rough models and prototypes. They are made from waste paper, and the clay is also made from already set waste plaster.

Because names like bio- and eco-board and clay were already taken. Since both materials are made with paper, they were named after the person who is said to have invented paper. The invention of paper is attributed to Chinese court official Cai Lun in 105 AD. Earlier archaeological examples of paper have been found in China, though little is known about the craft of papermaking prior to Cai Lun. That is why these modeling materials are called Cai Clay and Cai Board, to not just honor the history of paper but to connect you, a prospective paper maker, to its millennia-long history. To remind us all that if we want the human race to survive for millennia more, we need to embrace regenerative technologies, be they historical or brand new.
