The Ringed Vessel is a planter created using a specially developed ‘hempcrete’ made by mixing hemp shiv (the woody stem of the industrial hemp plant) together with a clay and lime binder.
The base structure of hempcrete is completely hand built and free formed, making each piece custom and unique. As the Hempcrete hardens from carbonation, it will eventually petrify the hemp and form limestone. The nature of the material and its processes means it does not require to be fired in a kiln further reducing the embodied energy of each piece.
The structure is rendered with several layers of natural clay lime plaster to reach the finished surface. Hemp fibres and fine hemp shiv and powder are used as an aggregate in the plaster. The surface is sealed with natural sealant and linseed oil.
Vessels are watertight without drainage holes. The hempcrete material being vapour-permeable provides the perfect environment for happy plants.
The inside drop measurement is 33cm and the colour is 'natural white oiled'.
