    摘要： A glass material for enamel is provided that can be used to produce an enamel product in which a luster pigment does not dissolve in glass and can thus maintain its luster properties to provide a metallic texture and high surface gloss.
    The glass material for enamel in accordance with the present invention is characterized by containing a frit that has a composition thereof including 40 wt% to 60 wt% of silicon dioxide, 15 wt% to 35 wt% of boron oxide, and 18 wt% or less of one or more alkali metal oxides selected from the group consisting of lithium oxide, sodium oxide and potassium oxide, and a luster pigment for providing a metallic look.
