Abstract:
A ceramic color composition consisting essentially of, as represented by mass percentage, from 60 to 85% of a low melting point glass powder, from 15 to 40% of a heat-resistant pigment powder, from 0 to 15% of heat-resistant whiskers, and from 0 to 15% of a refractory powder, characterized in that as represented by mass percentage, the Fe content CFe based on Fe3O4 is from 1 to 35%, and the Mn content CMn based on MnO2 is from 1 to 24%, that at least one of the Cr content CCr based on Cr2O3 and the Cu content CCu based on CuO is not 0%, and CCr+CCu is at least 1%, that each of the Ni content CNi based on NiO, the Co content CCo based on CoO, the V content CV based on V2O5 and the Se content CSe, is 0% or larger than 0%, and that CCr, CCu, CNi, CCo, CV and CSe satisfy the following formula 1:CCr/8.5+CCu/23+CNi/3.3+CCo/0.71+CV/56+CSe/0.45&lE;1%â€ƒâ€ƒFormula 1.
