Stained glass patina comes in black and copper, with each needing a slightly different process. This stained glass tutorial concentrates on copper, with additional notes about what to do if using black 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 and helps prevent mouldy patina.

Scrub stained glass solder clean
  • 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
  • Next you have to polish the solder. Yes, you did read that correctly; polish first before patina.

Exposing The Polish and Wax Myth

Most people – including me many moons ago – were taught to polish last thing. But I’d like you to think again about this…

Polish contains an abrasive element. As such it is better used for the final clean before patina or wax. It gets rid of the very last of the grime off your solder lines. That’s why the cloth still picks up black dirt when polishing.

Some people complain that their final polish removes the patina they’ve just put on… can you see why this is happening? Correct; because the abrasive element removes the patina.

They go around in circles putting patina on and accidentally polishing it off.

Roadmap

After experimenting over the years with different polishes, patinas and waxes I have developed this roadmap:

Clean >> Polish >>> Patina (optional, if you want your solder lines a colour other than silver) >>> Wax

You may have to experiment with the different brands but I’m confident that this roadmap will help you produce a lasting shiny finish.

2. Polishing Tutorial

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.

Remove final dirt and grime with polish
  • 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 with this stage – only waxing left!

 

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. I’ve found that there’s always a degree of experimentation with stained glass!

Brushing stained glass patina on to solder
  • 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 Buff Up With Wax

Final wax of stained glass patina
  • Repeat 2. above, but this time using wax.
  • Let the wax dry completely before buffing
  • For ongoing sparkliness, simply repeat these Final Buff Up instructions every so ofter to make your panel as good as new.
