PROBLEM TO BE SOLVED: To develop coloring frit without prevented with glass components of soda-lime glass in the base glass and having approximated coefficient of thermal expansion and viscosity characteristics to the glass to form marbling patterns of a red-orange-yellow warm color series on a glass vessel having the soda-lime glass composition, and provide a glass vessel formed with marbling patterns of the warm color series at a low cost. SOLUTION: A frit uses a milky glass containing BaF2 crystal as a base glass in which CdS and CdSe are mixed in an arbitrary ratio as colorants to obtain clear marbling patterns in appearance and the coefficient of thermal expansion of the frit is brought to be (8.5-10.5)×10-6/ deg.C (50-350 deg.C).
