Make Your Panel Shine!

Polishing Lead Came

The final step of stained glass making really adds class to your panel. It is done after the black cement has dried and hardened.
The cleaning gets rid of any black cement that has squeezed out from under the lead came during drying. The polishing blackens the lead and the solder joins and makes the whole panel sparkle.

Stained Glass Making - Final Clean and Polish

1. Picking out

How far you go with this process is up to you. Some people spend ages on it, others prefer the ‘softer’ look of a leaded panel that has rounded puttied corners.

- Use the fid to remove any hardened black cement that has squeezed through during the cementing process.

2. Blackening the leads

- Squeeze a bit of the black graphite polish onto a piece of scrap sheetglass.
- Dab one of the shoe brushes into it. You don't want to get too much on to the panel.

Getting polish on the brush

- Brush along the lead came, taking care to cover the solder joints.
- Leave for half an hour to allow the graphite polish to dry.

3. Polishing the lead came

- Take the other (clean) shoe brush and brush both the stained glass and lead came.
- This needs quite a lot of effort. Work at it until you can touch the panel without getting black fingers.

That's it. Everything is shining and your stain glass panel is finished. All that's left to do is hang it in the window and invite everyone round to your house to admire it! Big congratulations :)
