Painting on Glass

I had a bunch of pretty glass bottles that I had saved over the past couple of years and I wanted to try painting them. I read somewhere online that you can paint on glass by mixing white glue and acrylic paint. I was excited to give it a try. I didn't measure anything, but the glue to paint ration was about 1:1. I really enjoyed the technique. The look of the finish is painterly and still allows the light to shine through. I could probably add another layer to eliminate the streakiness. I don't think that my painted vase could be submerged in water, but it was able to withstand a wet paper towel.
