patina recipe

Just curious, why "re-invent the wheel"? buy it ready made.

It is far cheaper to produce big quantities than make a little bit.

Copper sulfate and warm water, make super saturated solution by mixing while warm = copper patina

copper sulfate, water and muriatic acid,(small amount, test alot) = black patina

there are, no doubt, other formulas and variations of these,this is just a base beginning spot.

bronze? mix the black and dilute with water alot, put it on weak and "build" to color you want.

Thanks

Unfortunately it´s difficult to find supplies for stained glass work in Sweden, most of the tools I have bought by Internet in USA. But we do have drugstores and hardware stores, thats why......

In that case, here is what I would recommend,

Instead of mucking your solder with chemicals, use an old trick, that still works quite well, and looks great, without adding more chemicals to your shelf.

When you build a panel with lead cames, you cement/grout/ putty it to fill the gap between lead and glass to weather proof the panel. Use the same material, but thin it alot with turpentine/TRPS and use a NATURAL bristle brush. Put a small amount to the thinned cement (made with lamp black?) on the brush bristles and buff the panel with that "patinaed" brush, your solder will gain a very nice, dark pewter color in very short order.

With copper,you still use the copper sulfate.

an old floor polishing machine does wonders for this Bart.

Only if I want to catch it as it flies across the room!! Sometimes "high tech" ain't.

Flies don't polish worth a darn :) A while ago there was a discussion about them small floor polishers that were popular in the

70's, the ones with two six inch brushes. I just lay the glass panels on a piece of cardboard on the floor and they buff up the cames to a real nice and almost pitch black shine. Properly made & puttied panels (gotta wait till the putty is cured) are plenty strong enough as there's very little weight put on by the polishing machine. Yup, sure works real sweet and haven't broken a panel yet.

Why not use a natural bristle round brush with your electric drill?

i do that. it wears out the drill pretty quickly as it's not made for spinning and applying that much pressure to that much weight. it's also hard to get an adapter to fit the drill and if it's a little offcenter, a bear to hold onto.

This machine has natural bristles and it's real quiet. Besides, being able to let it "ride" over the panel and "steering" it with only one hand leaves the other hand free for mr. coffee cup :)

I have one of those machines around, and I intend to give it a "spin". The only thing that worries me is that it's pretty heavy.

The weight is distributed over the surface area of the brushes so in terms of PSI there's hardly any, you'll be amazed at how black the cames polish up to.
