Portuguese dinnerware is, more likely than not, is hand-made and hand-painted by artisans in Portugal. Back in 1755, a horrible earthquake followed by a tragic tsunami destroyed much of the country. Reconstruction and relief efforts included not only rebuilding the country, but creating hand-made ceramic stoneware dinnerware. Today, a lot of different types and styles of dinnerware come from that area, including casual and fine china dinnerware sets.
Portuguese pottery, stoneware and ceramic dinnerware makes up a lot of the dinnerware market of dishes made in Portugal.
Casafina is a dinnerware company who is best known for their Casa Stone line which is Portuguese stoneware that is simply gorgueous.
Vista Alegre is a well-known porcelain manufacturer in Portugal. The dinnerware sets produced by this company is amazing.
Costa Verde is another company that distributes porcelain china from Portuagal.
Mikasa also distributes fine china dinnerware that is made in Portugal.
Spal offers a modern porcelain dinnerware set which is made in Portugal.
Occasionally, I see Portuguese dinnerware pieces in antique stores and gift shops. Many of the hand-painted pieces are marked "for decoration only" which is pretty standard for pottery dinnerware that is not produced with the intention of use for food consumption. These are the unique, artistic pieces that I find to be interesting for home décor.
A lot of the hand-painted dinnerware from Portugal is very vibrant made with bright colored paint. The patterns are rather elaborate. I find it comparable to Mexican Talavera pottery which depicts awesome talent with intricate designs.
