Porcelain Cog | SFAI 17 – 27 May ’19

This work is inspired by historic wooden cogs from the Wheal Martyn China Clay Museum, in St. Austell, UK. The wooden cogs are hand-made positives from which steel cogs were fabricated using sand casting techniques at the nearby Charlestown Foundry. The resulting cogs formed components for the drilling and water pump systems used to mine and sift out impurities from the clay.

I was interested in casting the object using the very material the cog was designed to process (kaolin, the primary component of porcelain), to create a feedback loop between product and tool. 3D printing techniques were used to create positives for the plaster molds for this process, drawing connections between contemporary and historic industrial processes and materials.
