ShrinkSan - The New Sustainable Kiln Furniture for Sanitaryware Developed by Imerys
6 August 2021
In a traditional firing process, sanitaryware pieces are placed on kiln furniture to proceed to firing. The extreme heat causes the ceramic piece to shrink, which creates friction with the kiln furniture, sometimes resulting in defects such as glaze chipping or foot deformation on the fired piece.
To reduce the occurrence of these defects, single use tiles are placed between the piece and the kiln furniture. While this solution has proven its efficiency, its environmental impact is questioned, as single used tiles are increasing the manufacturer’s waste.
Imerys has decided to address this issue and has developed ShrinkSan, a patented kiln furniture system able to cope with the piece contraction during firing while being reusable and therefore sustainable.
