The Casa Stone® Story Our Casa Stone line of fine Portuguese stoneware has set the standard in casual dinnerware with its distinctive but functional patterns that are oven-to-table, freezer and microwave safe. Casa Stone is made in a new state of the art facility in northern Portugal. It’s a completely safe and clean work place, and adheres to current environmentally sound procedures. There are more than 50 steps that go into making every piece of Casa Stone. Skilled artisans take great pride and care in producing our fine products. Because Casafina products are made and decorated by hand, there are variations in colors. We consider this an inherent aspect of their special beauty.
