Refrattari Valoriani’s ground breaking pizza oven design was patented in 1946 and became the blueprint for the industry. Today, each oven is still handcrafted by artisans in Tuscany. Andrea Mugnaini partnered with Valoriani in 1989 to define a range of pizza ovens for the North American market. Her genius was to merge elements of residential and commercial ovens to create the Mugnaini line of pizza ovens featuring key elements not found in any other brand.
