Over the years, I've dabbled in a lot of mediums and foundations to create artworks. I've painted jewelry boxes, candles, wood of all sorts, lecture stands, jackets, motorcycles and even lamps! (I learned how to use an airbrush to paint a motorcycle, it was a lot of fun.)
When I bought a house seven years ago, the front foyer window had this horrible painting of bluebirds on it that were rendered by an amateur using a media I had never seen before.
It was painted over the double paned window with a plastic semi-opaque paint that gave the appearance of stained glass. Or tried to...
It seems to me that this medium has a lot of promise to it. It doesn't suffer from some of the limitations of stained glasswork but it gives a similar effect. The glass doesn't have to be cut, meaning you can include a lot of details that are possible in traditional glasswork. It's really 'glass painting' as opposed to stained glass art, and it can be done for a fraction of the cost. And it wouldn't look cheap if you did it right.
After physically removing the old 'artwork', I set out to find out about my new prospective medium by looking on the internet and checking out art and craft stores. I found out that it's used mostly to create suncatchers and to create fake stained glass pieces on mirrors and windows (in a limited way)... By fake stain glass, I mean that the craftperson doing the work will use a pattern that simulates a stained glass pattern and follow it as closely as possible... This really wasn't what I had in mind for me!
So I bought some of the paint and blanks (wax paperlike plastic sheets) to practice on so that I could get a feel for the limitations and also figure out what I could do with it. I found that it dries quickly, but takes a day to clear out to the final colour. Meaning you can't see what colours you are really working with at the time you do the piece. This just makes it more challenging!
