What is the difference between a Memorial and a Tile?

A Memorial is porcelain with beveled edges.
Due to its dense nature, porcelain has a very low water absorption rate; making it resistant to freezing temperatures, and well-suited for exterior use.
A Tile is typically ceramic with squared/flat edges.  Ceramic is usually not durable enough for exterior use because it absorbs too much water.
If you live in areas which freeze, your tile could crack.
It is possible to request porcelain tile by Special Order.
