Porcelain tiles are typically made with very dense clays that have water absorption of 0.5 percent or less. Non-porcelain tiles (such as ceramics) use clays that have a water absorption greater than 0.5 percent. Ceramic and porcelain tiles are shaped clay that is fired at extreme temperatures in a kiln. There are both glazed and unglazed porcelain. Glazed porcelains are baked twice, giving them their durability and luster. Some people refer to unglazed porcelain as “through body” ( i.e., the color on the top goes all the way through). However, most porcelains made for larger surfacing applications have a pattern applied only to the surface (often during the glazing process), which gives them the countless pattern options, decreased porosity and increased durability.
However, with newer compact sintered surfaces, the initial manufacturing of the slabs use proprietary processes with varying temperatures and ingredients, so when the heat is applied, the material forms differently. Some manufacturers can form the slab in such a way that the material is uniform throughout — in color and pattern, whereas porcelain for larger surfacing options have the pattern typically printed only on its top, whatever the pattern may be. Also, some of these sintered surfaces were designed for countertop applications. So, the original design intent and engineering were meant to be for full-sized, durable horizontal or vertical surfaces.
