You can purchase porcelain knives in sometimes bright or black. The reason being the knives include zirconia. The black types are constructed of zirconium carbide and the bright people are produced from zirconium oxide. Whilst the knives are made a similar, the black kinds have a protracted firing process which create the zirconium carbide. The black knives are tougher compared to the white kinds; but, both knives are tougher than the usual material blade by about 7 to 10 times.
