Carbon coating of ceramic tiles was successfully carried out by placing the sample tile on the powder of carbon precursor, poly(ethylene terephthalate) (PET). Even the upper surface of the tile, which did not touch with carbon precursor directly, when about 0.01 g of PET per unit physical surface area of the tile was used. In order to coat the upper surface of the tile, it was required to be heated above 700 oC in inert atmosphere. The color of the surface after carbon coating was characterized by using L*, a* and b* (CIELAB). The lightness L* of the carbon-coated surface of the tiles was comparable with that of the commercially available roof tiles for Japanese houses. The addition of Fe2O3 in the precursor PET resulted in the formation of soot-like particles on the lower surface, giving a little lower L* value.
