This material is obtained by mixing ash with a natural glue binder. In the wet phase, the resulting paste has a consistency similar to that of modelling clay. This suggests a shaping similar to working with clay. However, as it dries, the material undergoes significant shrinkage, creating cracks that compromise the integrity of the volume. With further work on the material, I have observed that shaping it into studs gives it stability during shrinkage. This is why I chose to develop an extrusion shaping process. It is the shaping by hand, with or without support, of extruded rods. The strand is fragile but by multiplying the layers, the production acquires an increased resistance, which is suitable for domestic use.
