Every piece is made from pure porcelain clay — a material chosen for its density, smoothness, and ability to hold fine detail. Unlike standard earthenware, porcelain is non-porous and more durable, which means it stays cleaner for longer and holds up better over time.

Each piece goes through two separate firings. The first sets the form. The second fuses the glaze at around 1220°C, producing a food-safe, lead-free finish that is built to last.

Because every piece is shaped and finished by hand, small variations in form, colour, and texture are a natural part of the process. No two pieces are exactly the same.
