Forma Fabrica is a novel technique of slip casting porcelain in custom made reusable fabric molds. The method incorporates computer design and modelling of the ceramicware and the fabric mold while allowing customization and modularity. The fabric molds allow the extraction of the porcelain and create a unique subtle form of every vessel casted. The innovative technique can potentially serve as a sustainable substitute for plaster molds and create complex forms and undercuts that would be difficult to achieve traditionally.
