NEUTRAL BRONZE GLAZINGS

摘要

A neutral bronze sheet glass has a dominant wavelength in the vicinity of 575 nm, and a monochromatic transmittance which in the range from about 400 nm to about 550 nm is on the average from about 5% to about 50% lower than in the range from about 550 nm to about 750 nm, and possesses in thicknesses suitable for glazing a luminous transmittance above 70%.
