Patina problem

by imelda
(shipley, west yorks)

i urgently need some black patina but my supplier is closed today. I must have my piece ready today. can i use black shoe polish on the lead?


Answer

I don't know about shoe polish, I've never used it, but you can just buff the lead with a natural bristle brush (no polish necessary). The natural bristles will turn the lead black. It takes some elbow grease, but it's well worth the effort.

If you really want to use a patina, use stove black. Get the paste if at all possible, otherwise the liquid will do. If you get the liquid, it needs to be stirred well. I mean really stirred very well, shaking won't do.

Apply it with a soft bush like the one used for applying shoe polish. Let it dry, then buff it. Once it's dry, it will buff off of the glass (if you get any on the glass), and it will give the lead a beautiful black gloss. We use a lambskin pad on a buffer for buffing.

cleaning a combo piece of lead and foil

by Jackie
(Colorado)

I have created a piece that has both lead and foil. What is the best way to clean it and patina it so the piece looks consistent?

Answer

Clean the entire piece with CJ's Flux Remover. Wipe well with a damp cloth and dry. At this point you can either leave it all silver. Just wax it all and buff to a high shine. Or you can use black patina for solder on the foiled piece, followed by wax and buffing (on the foiled piece only). Then buff the lead with a natural bristle brush until it turns black...this will take some elbow grease. If you are going to use the black method, make sure you use black putty for the lead.

Patina Not Dark Enough on Lead

by john paul
(brampton ontario canada)

this is great,thankyou....i would like to know if there is any patina's out there that would react with lead that makes it very dark it seems the only one's from my supplier do not turn it dark enough....i think that the patina i purchase is diluted....also is it possible to find the ingedents {chemicals} used to make the patina

Answer
Rather than using patina try brushing the lead with a natural bristle brush after you have finished the putty process. If you use black patina, the brush will make the lead black as you vigorously brush it during the final clean-up. See my Putty Tutorial for a recipe for making your own black putty and how to use the natural bristle brush.

The chemical black patina for lead does not do a very good job. If you want to see the ingredients of all patinas made by Novacan, go here.

Many places, other than North America, use stove black to make the lead black. That is all we ever used when we had our stained glass business in Australia. It gave a beautiful deep black finish to the lead, and polished the glass in the process. Unfortunately, the product we used is not available in North America. However, if you have a wood burning stove business near you, you could experiment, with the stove black they sell, to see if it would work.

You need to literally splash it on the panel, then start scrubbing with a natural bristle brush until the lead is black and the glass is free of patina. Like I said, it is a messy process, but the outcome is beautiful and it gives a much deeper black then anything else available. If you can get paste stove black instead of liquid, it will be much easier to use. Just apply it with a brush used for shoe polish, then brush it until the lead is black and shiney.

Good luch with whatever method you try.
