Ceramics Glaze Made from Stone Sawdust

Studio Peipei has developed a sustainable ceramic glaze using stone sawdust. This innovation reduces the need for raw ceramic materials, lowering the environmental impact associated with traditional glaze production. By repurposing sawdust, a common byproduct in the stoneworking industry, the studio contributes to waste reduction while creating unique, organic textures for their ceramics.

The glaze is created from stone sawdust, a byproduct of stone processing that is often discarded. Rather than letting this waste accumulate or go unused, Studio Peipei has found a way to incorporate it into their ceramic production. By repurposing this byproduct, the studio reduces the need for newly extracted minerals typically required for conventional glazes, offering a more eco-friendly solution. The main ingredient in this recycled glaze is the sawdust from the Dichtl company in Southern Germany (62%), only 60 km from the studio, or from Barbany Artesans in Barcelona if there is a shortage.

The use of stone sawdust imparts distinct aesthetic qualities to the ceramics. Unlike standard smooth glazes, the stone sawdust glaze creates a rougher, more organic finish, characterized by irregular patterns and earthy tones. In addition, a key feature of this innovation is the constantly changing appearance of the glaze, which varies depending on the type of stone sawdust used. Different stones introduce new colors and structures to the glaze, creating a variety of shades, patterns, and textures.

Studio Peipei’s project addresses the environmental challenges posed by traditional ceramic production, particularly the mining of raw materials. The glaze does not require quartz sand, which is the main ingredient in most common glazes, since stone already contains enough quartz. By incorporating sawdust, the studio demonstrates how waste can be turned into a valuable resource, promoting a circular economy. This innovation serves as an example for how the design industry can adopt eco-friendly practices without compromising on quality or aesthetics.
