MARINEX Glass Bakeware production began over 50 years ago by SANTA MARINA, the largest glass manufacturer in Latin America. Located in Brazil, SANTA MARINA has been producing various glass products since 1895. The factory location is close to raw material deposits of boron and sand rich in color and quality. During the production process, these raw materials are combined using heat to make borosilicate glass. Borosilicate glass is resistant to changes in temperatures used in cooking and baking. With MARINEX bakeware, food can prepared, baked, served, and stored/frozen all in the same piece of bakeware. It is safe for both conventional ovens and microwave ovens. MARINEX Bakeware can go from the freezer/refrigerator to a pre-heated oven where the oven temperature does not exceed 100C or 212F to start. However, MARINEX Bakeware should not be used on stovetop burners or over a direct flame. This MARINEX & TEFLON medium 3.4 quart oval baking dish features DUPONT TEFLON Platinum non-stick coating.
