A glass composition, a cooking appliance having a glass composition, and a method of forming a glass composition may include a glass frit including 15 wt. % to 50 wt. % silicon dioxide (SiO2), 10 wt. % to 30 wt. % of diboron trioxide (B2O3), 5 wt. % to 35 wt. % of zinc oxide (ZnO), and 10 wt. % to 30 wt. % of an I-group oxide. The glass frit may further include at least one of aluminum oxide (Al2O3), zirconium dioxide (ZrO2), or titanium dioxide (TiO2) by about 0.1 wt. % to 5 wt. %; at least one of sodium fluoride (NaF) or aluminum trifluoride (AlF3) by about 1 wt. % to 5 wt. %; and at least one of cobalt(II) dicobalt(III) oxide (Co3O4), nickel(II) oxide (NiO), iron(III) oxide (Fe2O3), or manganese(IV) oxide (MnO2) by about 1 wt. % to 6 wt. %. The I-group oxide may include at least one of lithium oxide (Li2O), sodium oxide (Na2O), or potassium oxide (K2O).
