WebNote: Because the emissivity of a given material will vary with temperature and surface finish, the value in these tables should be used only as a guide for relative or differential temperature measurements. The exact emissivity of a material should be determined when high accuracy is required. Metals Index WebTypically, and certainly for silver, the 4d→5s transition has a large energy separation requiring ultraviolet photons to enable the transition. Therefore, photons with frequencies in the visible band have insufficient energy to be absorbed.

Ruthenium - With its flat black, gun-metal shine, ruthenium is a striking contrast next to polished metals. This makes it a perfect material in mixed metal jewelry. It is highly resistant to wear. raytech ms-75
