Valoriani Forni pizza ovens are made in Italy. The company has produced high-quality ovens for home and commercial use for generations. A central component: the chamotte floor. But what exactly is chamotte, how is it made – and why is it so important for pizza ovens?
What is chamotte?
Chamotte bricks are refractory, rock-like moulded parts. Chamotte itself is an artificially produced mass of raw clay with a proportion of aluminium oxide. It stores heat for a long time and therefore provides a lasting, stable temperature inside the pizza oven. The higher the aluminium oxide content (typically up to 45 %), the greater the heat storage. The melting point of chamotte bricks is around 1700 degrees Celsius – which is why they are classed as refractory.
How are chamotte bricks made?
Manufacture involves several stages. Raw clay is prepared, fired repeatedly, broken, ground, mixed again with raw clay and fired once more. This process yields a granulate with a composition characteristic to the manufacturer. The chamotte granulate is then pressed into moulds. Dry-pressed bricks are especially stable and heat-resistant.
Why use chamotte in pizza ovens?
Chamotte stores heat and releases it evenly to the dough. That supports consistent baking results — whether for fast pizzas or longer bakes. A well-designed chamotte floor is therefore a central component for temperature stability in the oven.
Made in Italy: chamotte production at Valoriani Forni
Valoriani Forni produces its chamotte granulate according to a family recipe kept for decades and presses the bricks at its own plant in Italy. This in-house production secures consistently high quality over the years and makes the company flexible and independent.
