AB  - Traditional golden red glasses were based on K2O-PbO-SiO2 composition system. In this paper, we reported new golden red glasses based on Na2O-CaO-SiO2 system without SnO2 and PbO in them. By using a spectrophotometer and chromamter color difference meter, it was found that the new glasses had similar optical properties to the traditional ones. The diameter of the gold particles in new glasses is around 40 nm determined by scanning electron microscope. The surface plasmon resonance created by the absorption of visible light emits golden red color. The benefits of using new golden red sodium calcium silicate glasses are the reductions of gold amount, cost and lead pollution to the environment.
