How sustainable is Bhar ?

Materials form the foundation for all innovations and power the development of cultures.


Recycling Bhars provides a use for the abundance of terracotta in India.

To intensify the value of the disposed of material and the recycling process, Collection Bhar includes naming the new resource. The powder-like material is called Terramittee.


Terracotta is a porous material that absorbs and stores liquids within a very short time. For these reasons, the discarded material is simple to grind and the new resource easy to manufacture.

Terramittee can be combined with raw clay to stabilise its quality and to increase its quantity. For ceramic designers it has an additional, creative value.

Ground bisque fired ceramics like terracotta (fired up to 900 degrees Celsius) are used in the international ceramic industry to enhance the raw materials’ quantity and to control properties.


Taking advantages of mixing ground low-fired clay with other materials — as exemplified by the industry — opens up various possibilities. Terramittee could be used profitably in various ways by potters producing Bhar as well as by local and international designers.






Inspiring diversity

Bhar, Kulhad, Kulhar. The same way the names differ, the shapes of the cups and the features of the clay vary according to regions and conditions. Each potter adds a personal signature related to taught technique, fingerprints, or inclusions. Each place has its unique clay which presents a recognisable colour and texture.

Experiments with Terramittee and white slip revealed unique patterns and textures which embrace an element of chance.


Each item includes an individual character according to the clay’s features, the grinding degree and the ratio of the mixed materials.

As a glaze or as a blend, fired at a 1240 degrees Celsius, created these fortuitous gradients.
