A pure clay that we dig straight out of the ground and grind into a powder. It is highly plastic and very smooth (fine particled) low temperature terra cotta clay. Its plasticity and dry hardness make it suitable in earth-mortars, green construction, pastes that need to be sticky and slurries that need to suspend well.
This clay has a low melting point. This makes it suitable as a bonding-agent or as an addition to bodies to reduce their vitrification range.
