copper 2 oxide

[orange2014]

I’m experimenting with chemicals that form bubbles in between sheets of glass. I’m aware of copper 2 oxide and the production of blue bubbles. I’m also aware of baking soda to produce clear bubbles. I am looking for another chemical that will produce clear bubbles. The problem I have with baking soda is that when I fuse it between sheets the bubbles do not extend to the edge of the sheet. Gas is escaping. Likely this is due to the baking soda evolving gas before the glass has softened enough to seal in the gas. It’s close though. That’s why most of the bubbles are trapped and only the ones around the edge are missing. What I need is a chemical that produces clear bubbles (evolves gas) at a higher temperature than baking soda.  This way all bubbles will be trapped right up to the edge of the work and will be better controlled. Any input from other members will be appreciated. Thanks, Kevin

You could try glycerine

Kevin,

I’m playing around with bubbles in glass, too. How did the glycerin work for you? How did you do it? – just brush it on between layers?

You could make the piece oversized and then trim it back to the bubbles.

I wrote a blog post this weekend about creating “controlled bubbles”. Perhaps my technique will give you some ideas:
