For five generations, the Henry family has been making tableware and bakeware in Marcigny, France. True to tradition all Emile Henry pieces are carefully crafted from Burgundy clay, found naturally in the region. The mineral-rich clay is combined with 100-percent natural ingredients to create a product unsurpassed for even heat distribution. Through the unique Ceradon process, each piece is fired with an extremely durable glaze that gives the finished product a naturally non-stick surface- which will not scratch from use or cleaning.
