How it started
The idea didn’t come from a materials lab — it came from a classroom in northern Uganda. A teacher had forbidden a child from writing in their notebook; the pad had to last the entire week. What looked like a pedagogical workaround was, in truth, a material question.
Back in Berlin, the first Stonepaper samples landed on the table. Waterproof. Wipeable. Made from a stone available in almost every region of the global south. It took two years for the sample to become a system.
What Stonepaper is not
Stonepaper is not a replacement for books. It is also not a premium notebook for European bullet journalists. And it is not anti-digital — those building a tablet school should keep building one.
Stonepaper is a tool for spaces where neither a book nor a tablet arrives. For schools with leaking roofs. For youth clubs where topics get discussed that cannot leave traces. For workshops that want to redraw their prototypes a few hundred times before they build them.
Who builds it
Stonepaper is organized as a non-profit gGmbH, but it works like an open research network. Each sub-quest has its own partners: materials researchers in Stuttgart and Kampala, teacher networks in Tanzania and Bavaria, workshops in Brandenburg and Zanzibar.
The recipes and build instructions are released under open licenses. Anyone wanting to build a Stonepaper Lab in their region gets access to the entire body of knowledge — and gives their findings back.
