摘要:
A clear glass, with the substantial absence of color in transmittance, and with an attractive, bright, edge coloration compatible with wood tone surroundings is achieved in a glass having greater than 85 percent, preferably greater than 87 percent, luminous transmittance by minimizing the amount of iron oxide present in the glass and including very small amounts of selenium and (optionally) cobalt oxide. Various warm, wood tone compatible colors at the edge can be attained, including a "honey" color and almost neutral grays.
