Sea FoodCeramic Tile One individual4.25" x 4.25" whitegloss standard grade ceramic wall tile.Kiln fired on Lowes #1224 American Olean Brand Ceramic white wall tile. All of our tiles and murals are kiln fired in temperatures exceeding 1400 degrees F and are made here at Mottles Murals in Youngstown, Ohio U.S.A. The standard grade wall and counter top tiles that the murals are kiln-fired onto are purchased at Home Depot or Lowes so you can easily match your tiles with no difference in size or depth of the individual tiles. The mural patterns are melted down onto the glaze of each tile during the firing process and the picture will not fade or wear off with age. This is not an ink press process this is a kiln firing process using china decals that are created with a silk screen process.
