Abstract
In order to provide an enamel frit composition capable of preventing a hue of a low-expansion crystallized glass plate of a dark color from being seen through an enamel coating without increasing the thickness of the enamel coating and the mixing ratio of a coloring pigment as well as to provide an enamel-coated low-expansion crystallized glass plate using the above-mentioned composition, the enamel frit composition for a low-expansion crystallized glass essentially consists, by weight, of 30-94 wt % glass powder, 5-69 wt % TiO.sub.2 powder, and 0.05-34 wt % coloring pigment.
