摘要：
A top plate (3) of a low-expansion crystallized glass of deep color, with a first enamel coating coated on a heating portion (5, 7, 9, 11) of the plate and a second enamel coating coated on a non-heating portion (13) around and other than the heating portion. The first enamel coating consists essentially, by weight, of 40 to 98% glass content, 5 to 55% at least one of ZrSiO.sub.4 and ZrO.sub.2 crystals, and 0 to 54% coloring pigment. The second enamel coating consists essentially, by weight, of 30 to 94% glass content, 5 to 69% TiO.sub.2 crystals, 0 to 34% coloring pigment.
