Questions About Leading
Non Lead Hobby Came
Do you still stretch hobby came like you do lead came?
Milly’s reply: This is a tricky question for me to answer, as you don’t say what the came is made of. Most non lead cames – zinc came and copper came for example – are used for edges of projects to strengthen them, and aren’t stretched.
Lead Glass Windows – Tight or Loose?
I’ve had a couple leading classes from a stained glass teacher who said that the glass should be ‘loose’ in the piece. Loose meaning if you put your fingers on it flat before it is puttied, you should be able to slide the glass back and forth a little inside of its lead came (not loose enough that it falls out). The idea being that you should allow for expansion. But I have had a couple failures after my projects are done and I’m wondering if it is because the glass was ‘loose’.
What is your experience when leading? Do you leave some room for expansion?
What happens if you have a ‘tight’ fit, ie the glass doesn’t slide at all?
Good question Lisa. You don’t say what your failures are, but I imagine they must be related to instability or sagging of the lead glass windows for you to link it to the tightness or looseness of the leading?
Your tutor is right in my experience – you don’t want the glass to be totally rigid in the lead, as there will be no ‘give’ in the glass panel and it will be more likely to hold tension and crack. A bit of movement will also give you room for more cement, which will add to the stability of your panel.
However, you really don’t want it too loose, as it will sag and be liable to crack too! As usual, there’s a balance to be had. Good luck in finding it.
Squaring A Stained Glass Panel
I have just built a panel. The size was to be within the range of 52 X 33 1/2. I find that the size is okay, but it is out of square. How do I correct this problem? I have one straight line – ( The wall, but it seems to be wandering away from the wall.) The measurement are okay, but it is not square. Help!
Milly’s reply: It’s a bit tricky to ascertain what to do here, without more information or a photograph. I’m not sure from your question whether it’s the frame that’s out of square, or your glass panel. And just how much of a gap you have, and whether it’s a uniform gap or uneven.
If it’s your panel, and you’re going to fit it in with beading and putty, you could always solder additional slithers of lead to the edges. They’ll be hidden in the installation process.
Sorry not to be of more help – I could probably offer more suggestions if you send me the additional information.
How do you support a glass circle project?
I have made 3 or 4 small stained glass panels and now may be a bit ambitious! but I want to make a circle panel to be put on top of a small glass top side table. It will be 55cm diameter. I have my design, but I am a bit of a loss how I start to build it up with no frame to support it like you do with a square panel.
I have cut a circle piece of glass as my middle, and then I want to build around that in a mosaic design. How do I keep it still and keep it all together as I make it? Do I cut and fit a few bits at a time and solder as I go ?
When you put together a square stained glass panel, you have the wooden batons nailed at right angles onto a board to support your glass for soldering. With a circle pattern it’s exactly the same principle, except you have half a circle cut from a piece of robust chipboard or MDF before nailing it onto a board.
The size of the half circle has to correspond with your pattern – i.e. the size of your table – in exactly the same way that your wooden batons do. You will have to take into account the edging material (lead, zinc came) and make allowances for the width of them.
The chipboard/MDF can only be up to half a circle, otherwise making the panel becomes impossible after a certain point, as you can’t fit the glass in.
If you have some very small, fiddly bits of glass, you can solder them separately before fitting them into the whole, but you have to be very careful that they’re accurately put together, otherwise everything will be pushed out of place.
Hope this explains it for you.
