What gives silicon that 'grey painted glass' look. No other element i can think of has such a distinctive color and surface texture.

Don't know where your getting your Si, but mine is a shiny metallic silver. Si is a semiconductor with a bandgap of 1.12 eV. If the stuff you've got is gray it most is likely a surface coat of SiO2 scattering the light. Try polishing it or etching it.
