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 different glass products since 1895. The factory location is close to raw material deposits of boron and sand which is 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. The raw materials also give Marinex glass bakeware a slight bluish tint consistant throughout all pieces. Marinex Glass Bakeware offers several shapes and sizes that have countless uses in culinary activities and are prominent by their beauty, durability, and ease of cleaning. It can be used to prepare, bake, and serve food as well as to freeze prepared food. It is safe for both conventional ovens and microwave ovens.
