Leaded lights may be made with lead from 6 to 16mm width (one quarter to five eighths inch) with a rounded or flat profile - the flat usually having a small bead at the edges. We can use regular 3 or 4mm float glass, which is very
flat and 'perfect', but often use a variety of horticultural glass, around 3mm, which has a less perfect surface, and provides a more traditional look. There are a variety of machine and handmade 'restoration' glasses available,
with small bubbles (seeds) and an irregular surface and thickness. This (expensive) glass may be used throughout the panels or intermixed with less costly glass, to provide an older appearance.

It’s important that the arrangement of the lead is such that long runs in one piece are avoided since that may introduce a weakness, since strength is conferred by ensuring that the are a number of instances of cross leading - a bit like
the way courses of bricks are arranged in a wall. Narrow thin steel strips may be concealed within the lead, edgewise to the glass to add rigidity. External support bars are also commonly added, set into the frame and 'hiding'
behind lead lines. The panel is fixed to these bars with copper tie-wires.
