摘要：
An apparatus for downwardly drawing glass ribbon comprises edge directors, wherein an outer portion defining a first pair of surfaces and a second pair of surfaces. In one example, the first and second pair of surfaces of each edge director includes a glass wettability with a static contact angle within a range of from about 30° to about 60°. In another example, the outer portion comprises a platinum alloy including from about 0.05 weight % tin to about 5 weight % tin. Methods for forming glass include the step of providing the edge director with a desired glass wettability and/or a desired platinum alloy.
