A vehicle windshield with a two-dimensional code includes a first glass, a second glass and an intermediate film provided between the first glass and the second glass. The first glass includes a first surface facing the exterior of a vehicle and a second surface adhered to the intermediate film, while the second glass includes a third surface adhered to the intermediate film and a fourth surface facing the interior of the vehicle. Black enamel paint is printed on the second surface and/or the fourth surface. The second surface or the fourth surface is provided with a two-dimensional code printed with enamel paint at a position corresponding to the black enamel paint. The two-dimensional code contains unique information of the glass and/or the vehicle.

An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include 15 to 50 wt % of phosphorus pentoxide (P.sub.2O.sub.5); 5 to 20 wt % of one or more of lithium oxide (Li.sub.2O), sodium oxide (Na.sub.2O), or potassium oxide (K.sub.2O); 1 to 5 wt % of one or more of sodium fluoride (NaF), calcium fluoride (CaF.sub.2), or aluminum fluoride (AlF.sub.3); 1 to 35 wt % of one or more of magnesium oxide (MgO), barium oxide (BaO), or calcium oxide (CaO); and 5 to 30 wt % of one or more of manganese dioxide (MnO.sub.2), molybdenum trioxide (MoO.sub.3), bismuth oxide (Bi.sub.2O.sub.3), or nickel oxide (NiO). The enamel composition may be cleaned without being putting it into water.
