What a great addition to any Brazilian Clay Collection then these clay bowls. They come with their individual wire trivets and are great for serving those Brazilian specialties. Of course, since they are clay, they can go onto heat or in the oven for au gratin recipes. Originally made by the indigenous people in the coastal regions using black clay and mangrove tree sap which resulted in very rustic pots. Today, our artisans use similar techniques and raw materials, however, they are molded to produce uniform sizes and shaped, and are kiln dried which makes them harder and more resilient.
