KOKSS creates its diverse line of cast iron cookware through an age-old process called sand molding. A proprietary mix of molten pig iron, steel and other ingredients are poured into a mold made of sand. Since sand melts at a higher temperature than iron, the mold holds its shape. Once the cast iron pan or pot has cooled, the sand mold is broken, leaving behind a brand new piece of cast iron cookware. Sand molding has been around since 680 B.C. It remains the best and most practical way to cast iron cookware.
We add a mixture of pig iron, recycled steel, castings from our foundry, and alloys to the electric induction furnace. This furnace runs over 2,000 degrees F and it can hold 10 metric tons of liquid iron. It takes 45 minutes for a 22,000-pound charge of metal to liquify.
Watch the videoTo make our cookware, we must first start with a pattern. We use the Disamatic molding machine to press a mixture of sand, water, and clay against the pattern and create molds. Each machine is capable of making 350-400 molds an hour.
Watch the videoOnce the sand mold is created and the molten iron hits the right temperature, we pour the liquified metal into the mold. Since sand melts at a higher temperature than iron, the mold holds its shape.
