Eggshell Ceramic
Unit Lab x Materiom
description
We will use an open source recipe by Materiom to make a ceramic like material from eggshells and a binder called Xanthan Gum. The washed eggshells are ground down into a powder-like material and then mixed with the binder. This makes a smooth material that can be 3d printed and extruded into many shapes and objects. We will make piping bags which are usually used in baking to extrude 3 dimensional objects that can be worn as jewellery.
