We encounter the union of bread and ceramics every day, mostly at the breakfast table. It is also not uncommon to see how bread is transformed from food for humans into a habitat for mold. Bread streaked with fungal spores not only ends up in the household, but often also straight from the supermarket shelf in the trash.

Fusion of ceramics and bread, new bowls
A new type of glaze for ceramics was created

How can this bread be used further? How can a new connection arise between the biological matter of bread and its decay with the geological matter of ceramics?


ceramics and the processes behind it fascinate us. For the production, the so-called shards are usually fired twice at temperatures of up to 1280°C. At these temperatures, organic components usually burn without leaving any residue. We wanted to find out whether this is actually the truth. The starting point of our experiment was bread, which was no longer usable for human consumption due to the incipient mold infestation. Instead of throwing it away, we let the bread and its mushrooms flourish in a slightly damp twisted vessel. After some time in the new home, we could hardly see the bread slices in their original breadth life. Rather, they now reminded us of green landscapes. After the firing of these vessels – including their landscapes – a new surprise awaited us.

Contrary to all statements and experiences of the experienced ceramists, not all organic components burned. Rather, the result is a fusion of bread and vessel. The result is bowls that have absorbed the remains of the bread like an “essence”. The visual appearance of the structure and appearance of the resulting surface is reminiscent of CO2 bubbles that rise from the dough during proofing.

In this process, the gloss is also created in the firing process. Usually, the gloss on the ceramic is created by glaze. The glass particles contained there are melted onto the ceramic in the fire. Despite the aesthetics, there is a major disadvantage of ceramics – recycling. In combination with glaze, the otherwise organic ceramics become hazardous waste. In the »mold pots« approach, we dream of finding a way to produce a recyclable object with a glaze-like surface. And maybe we can soon put our own sourdough bread in the bowls.
