Cordierite is a type of mineral commonly used in the production of refractory materials, including those used in the construction of pizza stones and kiln shelves. It is a magnesium aluminum silicate with excellent thermal shock resistance and high temperature tolerance. Cordierite has a low thermal expansion coefficient, meaning it can withstand rapid changes in temperature without cracking or breaking. This makes it an ideal material for pizza stones, which need to endure the the rapid temperature changes when pizzas are placed and removed. Cordierite pizza stones distribute heat evenly, absorbing and radiating it to create a crisp and evenly cooked crust. Additionally, cordierite has good porosity, helping to absorb excess moisture from the dough and prevent sogginess. Its durable and heat-resistant properties make cordierite a popular choice for achieving professional-quality pizzas at home or in commercial pizza ovens.
