Patina and Polish
For A Sparkling Finish
This stained glass tutorial shares expert tips on polishing and applying patina to copper foiled projects. This is the last thing to do before hanging your finished panel up for everyone to admire. It takes a fair bit of effort, but – as always – is worth spending time on to get a sparkling even finish.
If you want to avoid the disappointment of white residue and an uneven finish my Stained Glass Made Perfect online class can help you. Take a look and see if it’s right for you here.
Stained glass patina comes in black and copper, with each needing a slightly different process. These instructions concentrate on copper, with additional notes about what to do if using black patina.
What You Need
- Green scrubby
- Copper Patina

Stained Glass Tutorial – Patina and Polish
1. Cleaning Tutorial
It’s very important to do this thoroughly to remove any acids from the flux. Baking soda in the water can help reduce the white ‘crusting’ that sometimes forms. Some people swear by copper sulphate for cleaning. If you don’t have access to water you can use Flux remover Kwik-Cleaner . It works really well.
- Clean all the flux off the solder with all purpose cleaner. You can buy flux remover for this, but all purpose cleaner works just as well
- Put lots of cleaning fluid on and make sure it froths up
- Go over every solder seam thoroughly. You can use a toothbrush if it helps
- Dry it off with a paper towel
- Your solder should now be silver
2. Polishing Tutorial
Next you have to polish the solder. This might seem a bit back-to-front, but I’ve found the copper patina to take better over polish. It gets rid of any unseen dirt and grime. I use a standard car polish. If you’re using black patina, you don’t need to polish at this stage, go straight to 3. below.
- Put some polish on a soft rag and rub over the panel
- Keep buffing it up until the black residue all but disappears (where does all that black come from?!)
- If you want your panel silver, you’re done!
3. Patina Tutorial
Some people have trouble with patina being dull or not ‘taking’. This could be down to minerals in the water where you are. If this is the case, try buying distilled water and using it for the final rinse.
- With a Q-tip or cheap brush, apply the copper patina to the solder seams.
- Don’t be mean with the patina, and make sure that you cover every last bit of the solder
- Dry thoroughly with paper towel
- Let the panel air dry before the final polish with wax. I leave mine on my easel so that both sides can dry
4. Final Polish With Wax
- Repeat 2. above, but this time using wax.
- Let the wax dry before buffing
- Your glasswork will suffer from oxidation in time, sadly there’s nothing to be done about that. When this happens, simply repeat these Final Polish instructions to make it as good as new.
At 9 minutes, this stained glass tutorial is a bit long, but if you come in at 2mins 30secs you’ll hit the most useful bit. It’s definitely worth watching.
