A glass member for a housing of an electronic device may include an aluminosilicate glass substrate defining a first surface of the glass member, the first surface having a first surface roughness, a fused composite coating bonded to a portion of the aluminosilicate glass substrate and defining a second surface of the glass member, the second surface having a second surface roughness greater than the first surface roughness, a first ion-exchanged layer extending into the glass member and through the fused composite coating, and a second ion-exchanged layer extending into the glass member from the first surface. The fused composite coating may include an amorphous glass matrix and a crystalline material dispersed in the amorphous glass matrix.

The present invention provides a ceramic color composition which comprises, as a solid powder, 50 to 90 wt. % of a mixture containing 5 to 95 parts by weight of a first lead-free glass powder comprising at least SiO, ZnO, and BOas glass components, and 5 to 95 parts by weight of a second lead-free glass powder comprising at least SiO, BiO, and BOas glass components, 10 to 40 wt. % of an inorganic pigment, and 0 to 10 wt. % of an inorganic filler. The composition is free of lead and exhibits an excellent mold release property during the heat-molding process of a glass plate having the composition printed thereon. After firing, the composition is excellent in acid resistance, coloration in the bus bar portion, and plating resistance.
