The workshop sits on a quiet hillside outside Caldas da Rainha, a town in central Portugal with a ceramic tradition stretching back to the fifteenth century. Inside, the air is cool and faintly mineral — the scent of wet clay and kiln dust. It is here, in this unassuming building of whitewashed walls and terracotta floors, that many of our most beloved pieces begin their journey.

Master ceramicist João Ferreira has worked with clay for over thirty years. His hands move with the economy of long practice as he centres a mound of stoneware on the wheel, drawing it upward into a vessel that seems to emerge fully formed. "The clay remembers everything," he says, pressing a thumb into the rim to create the signature organic edge that distinguishes each piece. "Every hesitation, every moment of confidence — it is all recorded in the finished form."

After throwing, each piece is left to dry slowly — never rushed with artificial heat, which can introduce stress fractures invisible to the eye but devastating in the kiln. The drying room is lined with wooden shelves holding dozens of vessels in various stages of readiness, their surfaces shifting from the dark grey of wet clay to the pale buff of bone-dry stoneware over the course of several days.

Glazing is where artistry meets chemistry. The studio develops its own glaze recipes from raw materials — feldspar, silica, wood ash — and the results are colours and surfaces that cannot be replicated by commercial preparations. The sage green that has become one of our signature tones required over forty test firings to perfect, each variation meticulously documented in a leather-bound notebook that João keeps beside the kiln.

The final firing takes place in a gas kiln at temperatures exceeding 1,280 degrees Celsius. At these extremes, the clay vitrifies — becoming dense, waterproof, and resonant. When João opens the kiln door the following morning, there is always a moment of suspense. Not every piece survives. Those that do carry a depth and luminosity that only high-fire stoneware can achieve — objects that will outlast the generation that made them.
