Item Details
How waste can be turned into something useful and beautiful. The COFFIRE project might offer an answer.
The COFFIRE porcelain pendant light through the innovation of surface finishing technique by using used coffee grounds as sustainable coloring material to form mimic textures of marble under the mass production scenario.
The eco-conscious method of staining is inspired by the ancient pit firing technique for pottery making. During the low temperature (700-1000℃) firing process, the interaction between the biodiesel and the sugar in the coffee grounds, which oxidized to red matter, leave on the surface of the ceramics to form random texture, because the surface texture is influenced by many variables, such as temperature, humidity, coffee grounds density, etc.
The aim of the COFFIRE project is to develop the ‘imperfect’ design language from the perspective of the relationship between industrial standardized production and the craftsmanship.
This is a completely new and sustainable staining technique for porcelain product. Compared with the traditional pit firing, which tends to use toxic metals as coloring materials, the coffee grounds coloring ensures the safety of the product. In addition, this project replaces the traditional sandpit by gas kiln to achieve mass production, solving the problem of high waste rate of traditional pit firing. Also, the translucency of porcelain can add a form of presentation to the texture effect of the surface.
