Abstract
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 P2O5; 1-20 wt % of SiO2; 1-30 wt % of B2O3; 10-30 wt % of at least one of Li2O, Na2O, and K2O; 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.
