Recently I've been getting ready for my first craft market (24-25 Oct 2026 in Farnham) which has given me an excuse to play with some new techniques.
One of the things I've been playing with is creating bubbles in glass.
My favourite reaction is with Copper Oxide which created lovely blue bubbles. Adding more makes the colour deeper but also makes the bubbles more unpredictable. Using less powder might mean a lighter colour but also makes the bubbles more uniform.
This stuff is strong. It's suggested that you mix it with clear glass powder before using.
But what if I don't want blue bubbles?
I got given a whole bunch of glass supplies when I bought a tool off someone who was giving up. In this mix was a bottle of Bubble Powder. No instructions so I had to do a little investigation. And I found that I could mix this with different coloured powders to create bubbles like the Copper Oxide but in the colour of my choice.
So I gave this a go too.
I started by making some glass blocks to make into earrings. You take two pieces of clear glass the same size. Sprinkle the powder mix on one sheet of glass, and put the second on top.
Now do a full fuse. You will have a sheet of glass full of bubbles.
Next cut the sheet up into earring sized chunks. This is easier said than done. Also within my sheets I had a few bigger bubbles, so I cut these to make pendants. Lay them all out so they aren't touching and run them through another full fuse.
Now you have lots of blobs full of bubbles which you can add earring backs to and voila, you have yourself a set of funky earrings.
I spent a lot of time matching size and colour to make matching sets. But there were a few were the colours didn't match but the size did. I'll be interested to see if anyone buys them.
Of course I couldn't stop there.
I really wanted to make a dish. So I bought 2 pre cut circle sheets (big circles are hard to cut) and added some Copper Oxide. A full fuse later and I had a sheet of very bubbly glass! I then slumped it into a bowl shape. I'm still amazed at what you can do with glass!
Once the market is done I'll have a bit more time for some other projects that have been on my list all summer! Looking forward to it.
