The present invention relates to an enamel composition capable of removing sugars as well as poultry oils as contaminants at a low temperature by using a catalyst oxide, to a manufacturing method therefor, and cooking utensils. The present invention provides an enamel composition, a manufacturing method therefor, and cooking utensils, wherein the enamel composition is capable of removing sugars as well as poultry oils as contaminants at a low temperature by comprising: at least one of SiO.sub.2, B.sub.2O.sub.3, Li.sub.2O, Na.sub.2O, and K.sub.2O; and TiO.sub.2.

The present disclosure relates to non-metallic articles that can be burner shields having grease flow control and/or chemical resistance. The present disclosure also relates to glass-ceramic burner shields that can have grease flow control and/or chemical resistance, and preferably both.

An enamel composition having improved cleaning performance, a method of preparing the enamel composition, and a cooking device having the enamel composition are disclosed. The enamel composition includes glass frit and a metal oxide catalyst, wherein the metal oxide catalyst includes at least one of a unary metal oxide or a binary metal oxide, thereby allowing cleaning at room temperature while exhibiting good fouling resistance to allow easy removal of oil contaminants, such as chicken fat.

An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include silicon dioxide (SiO.sub.2) at 25 to 50 wt %; boron oxide (B.sub.2O.sub.3) at 1 to 15 wt %; one or more of lithium superoxide (Li.sub.2O), sodium oxide (Na.sub.2O), or potassium oxide (K.sub.2O) at 10 to 20 wt %; sodium fluoride (NaF) at 1 to 5 wt %; zinc oxide (ZnO) at 1 to 10 wt %; and one or more of titanium dioxide (TiO.sub.2), molybdenum trioxide (MoO.sub.3), bismuth oxide (Bi.sub.2O.sub.3), or cerium dioxide (CeO.sub.2) at 20 to 40 wt %, such that a heating time required for cleaning is shortened and cleaning is possible without carrying out a water soaking process.

An enamel composition for a cooking appliance is prepared by a preparation method. The enamel composition includes glass frits, a siloxane-based compound, a silane-based compound, and mill addition. The mill addition includes one or more materials selected from a group comprised of SiO.sub.2, Al.sub.2O.sub.3, ZrO.sub.2, and TiO.sub.2, thereby suppressing defects such as chipping even when the enamel composition is used at high temperature, for pyrolysis of contaminants.

There is disclosed a novel enamel composition that may be applied to all diverse components for a cooking appliance, with excellent cleaning performance and adhesion. The enamel composition of the present disclosure may include 10 to 25% by weight of SiO.sub.2, 15 to 30% by weight of P.sub.2O.sub.5, 1 to 15% by weight of B.sub.2O.sub.3, 10 to 25% of at least one of Na.sub.2O, Li.sub.2O and K.sub.2O, 1 to 5% by weight of NaF, 15 to 35% by weight of at least one of Al.sub.2O.sub.3, TiO.sub.2 and ZrO.sub.2, and 1 to 10% by weight of at least one of Fe.sub.2O.sub.3, Co.sub.3O.sub.4 and NiO, thereby being applicable to coating of components for a cooking appliance such as a burner cap, a grate and a griddle in which food is vulnerable to contamination and subject to thermal shock.

An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include 20 to 50% by weight of silicon dioxide (SiO.sub.2), 7 to 12% by weight of boron oxide (B.sub.2O.sub.3), one or more of lithium superoxide (Li.sub.2O), sodium oxide (Na.sub.2O), or potassium oxide (K.sub.2O), and 10 to 20% by weight of sodium fluoride (NaF), 1 to 10% by weight of zinc oxide (ZnO), and one or more of molybdenum oxide (MoO.sub.3), bismuth oxide (Bi.sub.2O.sub.3), or cerium dioxide (CeO.sub.2), and 10 to 40% by weight of titanium dioxide (TiO.sub.2). With such an enamel composition, cleaning is possible in a heating condition of a relatively low temperature and without a soaking process using water.

The present invention relates to an enamel composition capable of removing sugars as well as poultry oils as contaminants at a low temperature by using a catalyst oxide, to a manufacturing method therefor, and cooking utensils. The present invention provides an enamel composition, a manufacturing method therefor, and cooking utensils, wherein the enamel composition is capable of removing sugars as well as poultry oils as contaminants at a low temperature by comprising: at least one of SiO.sub.2, B.sub.2O.sub.3, Li.sub.2O, Na.sub.2O, and K.sub.2O; and TiO.sub.2.

The present invention relates to an enamel composition capable of implementing cleaning without swelling using moisture, to a manufacturing method therefor, and to cooking utensils. The enamel composition according to the present invention comprises: 20-60 wt % of P.sub.2O.sub.5; 1-20 wt % of SiO.sub.2; 1-30 wt % of B.sub.2O.sub.3; 10-30 wt % of at least one of Li.sub.2O, Na.sub.2O, and K.sub.2O; 10-40 wt % of at least one selected from the group consisting of post-transition metal oxides and transition metal oxides. Therefore, the present invention provides an enamel composition capable of implementing cleaning without swelling using moisture, a manufacturing method therefor, and cooking utensils.
