Methods: 48 casted Ni-Cr alloy metal specimens (12.0 mm×1.0 mm) were fabricated with ShoFu Vintage Halo porcelain and divided into six groups, eight pieces for each group. They were polished against 200-, 400-, 600-, 800-, and 1, 000-grit sandpaper after body porcelain sintered, respectively. The specimens in a sixth group not polished was used as control. Surface roughness and Color parameters of the specimens were measured with a Surface Roughometer EX2154-13 and a spectrocolorimeter respectively.
