Method for making simulated beveled and leaded glass window structure

The method of preparing a simulated beveled and leaded glass window structure comprising:

• a. forming a plurality of beveled grooves having flat beveled sidewalls with sharp edges and optical quality smoothness along the front face of a plate of substantially clear or translucent glass or plastic having a smooth front side and a smooth reverse side to subdivide said plate into design segments of unrelieved pane thickness surrounded by beveled grooves, and providing each groove with a sidewall angle from 10 to about 70 degrees and with a flat bottom wall having a width from 0.1 to about 0.6 inch;
• and
• b. inserting a plurality of lead strips having a width about equal to the width of said flat bottom walls and flat undersurfaces into each of said grooves and bonding the flat undersurfaces of said lead strips to said flat bottom walls of said grooves, thereby enclosing said design segments with said lead strips.
