White Glass Opti-White

The white glass Draenert delivers differs in the clarity, because the greenish light refraction of the standard float glass has disappeared almost completely. The glass edges still show in proportion to the glass thickness and pane size a blue-green colouring, but which is significantly lighter as the fir green edge of normal float glass. The edge colour is not visible on the very small sample panes in the sample case. The proof for standard float glass or white glass shows the view through the glass on a white sheet of paper. With standard float glass the sheet looks light green, with white glass the white sheet remains white.
