3D printed open source clay hardness tester launched

CFPR has launched a 3D printed open source clay hardness tester, an outcome of ceramics research undertaken by Dr Tavs Jorgensen and Sonny Lightfoot. The initiative aims to establish a common clay hardness standard, with the open source files and information published on the Wikifactory site.

CFPR’s contribution towards the clay hardness measuring standard and tool was inspired by the research of artist and potter Jonathan Keep and his Drop Spike design. The design is a combination of Drop Spike, the ‘Pig Sticker” – the penetrometer known from the clay industry as well as the ‘Fall Cone’ testing devise used in geoengineering.
