I use Diamond Glaze for many things, and always have some on hand. It dries very clear. I have found that I was able to use it to fix a vintage cracked vase to keep the crack from spreading. In addressing some of the other reviews, it can be difficult to get a raised bezel finish with this stuff. It does tend to sink, and you need to keep adding Diamond Glaze over a long period to get it to be even. When using it on any type of printed paper, be sure that the image is completely dry. I do not use matte paper, but the HP Brochure Glossy. I print it out (ink jet), and then let it dry for at least one day before applying Diamond Glaze and glass cabochons. To remove bubbles, trying using a smaller tip, and then gently press the glass down on the paper. You have a very tiny window to move the glass around on the paper before it sets. I have never had a problem with bubbles. An easier way to remove the paper from the glass, should you need to do so, is to use nail polish remover. Let it soak for ten minutes and the paper will slide off easily to use the glass again.
