DIY Clay PCB Tutorial: Making Circuit Boards with Porcelain and Wild Clay

To build the base of our PCB, we needed insulating, sustainable and robust materials (eggshells? wood plates? wax? ceramics?).

We immediately chose ceramics, specifically porcelain, as it already plays an important role in electronic components such as capacitors, piezo, resistors, and so on.

Porcelain is an industrially made material comprising kaolin (the main ingredient that makes it plastic and white) and stone pottery (the second ingredient that makes porcelain translucent and hard).

Both are well-known commodities that a
