Ceramic Tile: Ceramic slate
The Old House Web
The tiles can be used inside and out, including on walkways, courtyards, patios, and porches, both covered and open. The high-fire porcelain stone tile is virtually impervious to moisture, so it shrugs off the freeze-thaw winter conditions that cause slate to crack.
The tiles come in a larger 18" x 18" size similar to natural slate, as well as in 12" x 12" units. Surface bullnose and bullnose corners complete the new Vermont series.
