Leadlight vs Stained Glass: What’s the Difference?
People ring us asking about “stained glass windows” when what they’ve actually got is leadlight — and the other way round. They’re related, but they’re not the same thing, and knowing the difference matters when you’re getting one repaired or quoting a restoration.
After 16+ years working on glass across Adelaide, here’s how I explain it.
The short version
Leadlight is glass held together with lead. Stained glass is glass that’s been painted and fired — and usually held together with lead as well. So all stained glass is technically a form of leadlight, but not all leadlight is stained glass. The painting and kiln-firing is what separates them.
How they’re built
Leadlight is made from pieces of coloured, textured, or clear glass cut to shape and joined with H-shaped lead strips called cames. The cames are soldered at every joint, then the whole panel is cemented to make it weather-tight and rigid. It’s a craft job, but a mechanical one — the design comes from the shapes you cut and the glass you choose.
Stained glass adds another step. Details like faces, drapery, lettering, and shading are painted onto the glass with metallic-oxide paints, then fired in a kiln so the paint fuses permanently to the surface. That’s why a church window can show you a face, a robe, a scroll of text — none of that’s possible with cut shapes alone.
Where you see each in Adelaide
Leadlight is everywhere in older Adelaide homes, the Federation and bungalow stock through Unley, Prospect, Norwood. Front doors, sidelights, hall windows, the top sashes of bay windows — usually geometric patterns, floral motifs, sometimes a small painted centrepiece.
Stained glass in Adelaide you mostly see in churches, some of the older public buildings, and occasionally a feature piece in a grand home.
What goes wrong with old leadlight
The most common call we get is a panel that’s bowed out from the frame. Lead is a soft metal and it fatigues over decades — a 100-year-old leadlight panel that’s never been re-leaded is on borrowed time, even if it looks fine. The other thing we see is solder joints that have cracked, or the cement that holds it all weather-tight has dried out and started letting water in — that one’s a slow killer because you don’t notice until the timber frame’s gone too.
Repair vs replace vs restore
A single cracked piece can often be cut out and replaced without touching the rest of the panel. A whole panel that’s bowing or losing its integrity needs to come out and be re-leaded — the glass is reused, but the lead, solder and cement are all redone. Restoration of a stained glass piece with painted detail is a different job again, and we send those on to Adelaide Leadlight Centre.
If you’ve got old leadlight in your home
Don’t wait for it to fall out of the frame. The cheapest repair is the early one. If a panel’s starting to bow, if you can see daylight at the cames, or if you’ve got a cracked piece, get it looked at before the whole thing has to come out.
