Getting ready to get back into stained glass. As I recall, the ink from a “regular” Sharpie would “flake off” during the grinding process. Is there a pin with ink that will adhere better than a “regular” black Sharpie? If not, do you have suggestions to keep ink on the glass during grinding? Thanks!
You can smear over it with petroleum jelly or chapstick. Some people swear by Milwaukee Inkzall but I haven’t tried one yet. Alternatively, the metallic Sharpies stay put for longer. Nothing appears to be the answer… apart from cutting more accurately and doing less grinding 😉
We have a large stained glass eagle window which is beautiful. Had it since around 1986 and had incorporated it in our last home we had built and it looked good. My question is: since moving to this home we had a window put in over the garage for the purpose of holding the eagle (which we removed and brought with us). We have not gotten it illuminated yet but there is one section about 8×12 that looks like it is illuminated and stands out. Do you have any suggestions as to why this has happened and what we can do to fix it?
I can only think that it’s the colour of the glass that’s making it seem illuminated. Is it different colours in that section than other sections? Or perhaps there’s painted detail on all but that particular section, which makes the glass stand out and shows the colour more?
Sorry I can’t help more without seeing it.
I have never worked with stained glass. A friend of mine makes stained glass tops on stumps in her yard. They are beautiful. We are going to do that in my yard but could use a recommendation for an outdoor varnish that doesn’t yellow.
You can use wax on foiled work Sharon. Mothers is a good make. Sounds an exciting project, good luck.
Dear Expert Glasses,
We just finished up 2 stained glass pieces, and are ready to wax them. But we’re not crazy about the finish it leaves on each side. Sometimes it shines nicely, and sometimes not. Sometimes the glass sparkles and sometimes not. We are wondering if using something like spray on Pledge, and then polish it with a soft rag. Would that work very well to clean, polish and finish the piece? If not, what would you recommend?
Thanks for your feedback.
You can use Pledge for the glass as an additional ongoing buff up. This is my cleaning, polishing and waxing routine here:

P.S. Love the ‘Expert Glasses’ name, will have to adopt it! 🙂
I’m doing a window out of all textured clear glass for my front door. Which side of glass is usually on outside?
Great question Mary. I’d go for texture on the inside as it’s less likely to get dirt in it. The light refracts nicely through from the smooth side for those on the outside, and you’ll have the texture catching the light on the inside.
How come some of my longer lead lines look wobbly instead of straight?? It is frustrating!!!
Are you stretching the lead came sufficiently before you start, Bill? There’s some information on this if you scroll down this page: https://everythingstainedglass.com/stained-glass-lead
I hope that helps.
New to working with stained glass and can not find any answers to solve my problem. After cutting and grinding glass pieces there is a milky white residue left on edges. If anyone can advise me on how to remove this I would be so happy!
That’s the grinding process Joshlyn. It isn’t a problem with stained glass but as the foil tape or lead came hides it. It can be a problem if you’re fusing though as it can leave a ghost of a line. Best to cut and not grind if fusing.
I hope I’ve got the right end of the stick with your question.
Hi!
I’m looking for some kind of bender or machine that can make u cames from brass or copper strips. My vision is that you can cut out flat strips and then turn them into u cames. Do you know if that exists?
Best regards,
Johanna
Not to my knowledge Johanna. I know people who melt lead and make their own cames but not brass or copper. You need a fumigating set up and a dedicated press. You can buy it, a lot easier LOL.
Maybe someone else can help?
Hello my name is Carmela Brignolo and I’m looking for someone that I would pay to stain glass some of my glass items I’m tired of having to look through them I want to put color in my apartment.
Ty,
Carmela Brignolo
Hello Carmela, you don’t say what country you’re in? If you Google ‘stained glass studios’ you should find some in your area that will be able to help you. Sorry I can’t be of more help.
I am working on a stained glass piece that has some detail that will have to be painted on. Would it be best to paint directly on the glass (I don’t have access to a kiln) or use copper foil cut to the shape of the detail and paint that? If using copper foil, would I want to tin it first, or paint directly on the foil? Also, what would be the best paint to use for this? Thank you for this site! You are amazing and so helpful!!
You can use a ‘cold’ glass paint instead of the paints that need firing in a kiln. You can get them from Pebeo. If you want something a little more robust Pebeo sell glass paints that you put in your oven to bake on. They’re not permanent but better than the cold ones that don’t require heat at all.
You wouldn’t paint the foil, no. You can do an overlay with foil – which means cutting the foil to the detail shape and then soldering on. This detail is best if soldered to an edge or glued on, otherwise it’s liable to come off.
Good luck and thanks for your nice comments and questions Maria.
Would I paint the detail before foiling and soldering? Will the oven method harm or disfigure the solder?
Also, I have foil that is a couple of years old. One roll has been in a zip lock baggie and another has not been opened from it’s original bag. Will it still stick, or should I buy new? I would really hate to waste it…
It should be fine if it’s been kept air tight. I always advise testing things before you do your ‘real’ piece if you’re in doubt. You could foil a couple of scraps and leave it for a week to see.
I hope they’re okay, it’s a shame to waste them as you say.
If you’re painting and firing the paint on – either in a kiln or in the oven, do it before soldering. If you’re using ‘cold’ paint (that doesn’t need to cure with heat) do it after the soldering. The cold and ‘warm’ (oven paints) are more vulnerable than the solder Maria.
I hope that helps.
Thank you so much for your help!! I have found so much helpful advice and fun new things to try on your site! I will be getting to the how to videos soon! I very much appreciate all the time and effort you put into this site!! Can’t wait to explore more 🙂
I need to solder tinned copper wire on to lead came (meant to look like cactus spikes). I have tried various temps with my Haiko soldering tool but it will not work. The solder just rolls off the lead came (u) and will not adhere to the came. Anybody got any suggestions? Heeelpppp!,,,,
The lead came must be shiny and fluxed before it takes solder. Try brushing it with a wire brush first then fluxing and soldering straight away. That should work. Good luck!
I have applied black pantina to my piece it has a orange hue on all places where the pantina was applied do you what cause this problem how to fix so the piece is black can send a photo to better explain problem
Thanks Bill
It could be a variety of things, from chemicals in the water or oxidation. Black patina is a bit trickier than the other colours. Here’s a suggestion: wash the flux off with dawn soap and let the piece dry. Buff the solder with fine steel wool (wear gloves and a mask). Spray patina on a small area at a time and work in with a soft bristle brush. Allow it to settle for about 10 minutes. Then try shocking the piece with cold water before washing with dawn soap for the second time. When it’s dry, apply polish and once the haze forms, sprinkle whiting on the piece and work in with soft bristle brush. Vacuum off and then buff the piece with a soft clean cloth.
My copper patina tutorial is here if you need it at a different time.
I hope that helps your stained glass.
I left my soldering iron on overnight and now it has a black coating on it. It still heats up but isn’t working as well. Is there anything I can do to fix it?
Ooophs – we’ve all done it Lynn!
If you’ve tried all the tinning that you normally do and the coating is still damaged you’ll have to get a new tip I’m afraid. Not the end of the world – hopefully your iron will be okay.
I would like to have a stain glass panel to go over a window that has bars between the thermopane. Window is 50″x24″ with one horizontal bar & 10 vertical bars deviding window into 10 individual sections. My question is should glass panel be made with similar bars incorporated in design or can one large design be made to cover the 50″x24″ space? With the latter I am worried that bars would show through design & distract from an overall design. Could you suggest a design that would look right for this type of window?
The reinforcing for a window this size needs to be robust. It’s too big to make a window this size without bars so you’re stuck with them I’m afraid!
The good news is that when you think of a large Tiffany or a Frank Lloyd Wright stained glass window you don’t think of ‘bars’, you think ‘wow, beautiful!’. The colour and the design ‘override’ the bars in our minds’ eye.
With regard to design, I chose Tiffany and FLW deliberately as they are very different styles but both are possible with bars. What I would suggest is that you work out the bars along with the design right at the beginning. Don’t try to add them in at the end – that will end in a mess.
I would go with the existing bars.
This is a very good question Marlene, thanks for that. I hope this helps.
I need to find out if anyone has info about the possible contaminates that can be released when washing projects,like in your work sink, or outside with a garden hose? How does this not affect ground water?
It should be okay if you use a lot of water to dilute the small amount of chemicals. It’s not neutral as there are chemicals but they’re probably no worse than toilet cleaner 🙂
This isn’t backed up by any research or science, so if anyone else has any comments that would be great.
Thanks!
Hello,
I’ve seen beautiful “stained glass” windows made by adhering old crystal dishes, that haven’t been broken, to vintage windows. I am wondering what adhesive is the best to use? It would need to be strong and unaffected by weather and light. Thank you for your help.
Hi Kim, I like to fix the dishes in by using copper foil so the vintage plate becomes part of the stained glass window. You can learn more about this technique here.
I’ve never tried gluing directly on to glass so I’m not claiming to be an expert here. There are many transparent silicones that will stick glass to glass and not yellow over time but I’m wondering about the heat build up if this is going to be in the sun.
Can anyone else share ideas about the glue idea?
