Flashed Opal Glass Opal glass is a superior diffuser to ground glass because it depends upon the scattering of light by particulate matter suspended in the glass itself rather than a surface reaction. It is correspondingly less efficient in overall transmission.
Flat Glass ROLYN flat glass is of the highest commercial quality. Surfaces are 80-50 scratch-dig or better unless otherwise specified.
Ground Glass - Single Side Ground glass is used for diffusing light, and ROLYN ground glass is superior for this purpose because of its fine grind and evenness of finish. 500 Grit.
Pot Opal Glass Opal glass is a superior diffuser to ground glass because it depends upon the scattering of light by particulate matter suspended in the glass itself rather than a surface reaction. It is correspondingly less efficient in overall transmission.
