A good question from a colleague in Maryland, USA:
I am an experimental physicist in mid-career and very busy with work – so my time spent on stained glass and glass painting is very sporadic – it has been 8 or 10 months since my last project.
Is it OK to make the lump of paint (as you teach) and leave it for 6 months to a year?
Should it be tended to periodically over that time?
Will it “come back” and be usable after a very long time?
And the answers are …
So busy here recently what with …
Now our client had approved the 16 designs he’d asked for, and so it was back to us to secure his agreement on the painted glass itself – on what it must look like when it’s finished.
His insistence was, his skylights must look ancient.
And that is why we spent these last few weeks establishing and refining the necessary techniques to make the glass look very old.
Today the client’s architect called in to see the samples we had made.
The meeting went as well as you could wish.
So now we can reveal for the first time how the ancient-looking glass was stained – including a short video for you.
I’m glad the post on blistered paint (and how to stop it) was useful to you.
Afterwards, Ron Prondzinski made a really useful comment about Reusche’s water-based painting medium (D1368).
My response was:
What special uses does it have?
I mean, why use a manufactured medium rather than just plain water which we can all get from the tap?
I also thought:
I’m no dinosaur but …
Why haven’t I tried it yet?
