Perrin & Rowe fireclay sinks demonstrate the natural characteristics of fireclay ceramics and are created by a slip casting process. Whilst modern technology has improved manufacturing methods over the years, the principles of this handcrafted product remain the same.

Created by hand-pouring a mixture of clay and water into a porous mould, the newly formed sinks are dried, then removed by a craftsman from their moulds before hand finishing the sinks through a process of sponging and fettling to create a smooth finish. Following a gradual drying period of up to 40 hours, the sinks are then prepared with a ground coat before being glazed and fired in specially designed kilns at temperatures of up to 1200°C.
