ABSTRACT:
A glass pane has a broken pattern of dots of an opaque non-reflective material applied to one side thereof. The pattern is applied as a ceramic ink fused into the glass surface in a heat toughening step. The arrangement of dots is such that the pattern occupies 10% to 30% of the pane surface and comprises 30 to 50 dots per linear inch. A squash or like court formed from a number of such glass panes is such that players within the court are not distracted by spectators outside and can follow the path of a squash ball with ease, whereas spectators outside the court, by virtue of differential lighting as between court and spectator area, can watch the activity within the court without diminished vision.
