What’s the difference between glazed and unglazed porcelain tiles?

Generally glazed and unglazed porcelain tiles differ in their appearance. Glazed porcelain tiles usually have a subtle glossy glow, and unglazed porcelain tile has a matte or natural-looking finish. While still dense, glazed porcelain tile tends to be a bit thinner than unglazed porcelain. However glazed porcelain is more stain-resistant due to the coating that’s applied to the tile before it is finished via heating during the manufacturing process.
