Waste not Glaze

A CSM research project

Waste Not Glaze was built out of Emma Lacey’s design-led ceramics practice and a principle amongst students and staff on BA Ceramic Design to explore less extractive approaches to material sourcing.

This CSM-funded project examined whether methodologies for developing ‘circular’ or non-extractive ceramic glazes could be applied in a studio ceramics context.

The project outcomes were tested against notions of economic viability and glaze durability for safe use in commercial tableware and dining settings.

Three glazes were developed using up to 50% waste material from the glass and stone industries and tested at Lucideon in Stoke-on-Trent; passing UK standards for durability.

One of these glazes features in Emma’s designs for coffee cups for Fortnum & Mason, launched in store (Piccadilly, London) in January 2025.
