How do I get those bubbles?

If you are trying to create bubbles in your work, then doing what you call and extra ‘anneal’ on the upside of your firing is actually working against you… what you are calling an anneal is actually a bubble squeeze that is done to prevent bubbles from forming.
Just my 2 cents.October 21, 2010 at 3:11 am #11312cdchildsParticipant
I’m making my first attempt for bubbles in my next firing. I have used a fine powder frit on my base color of cream glass . Blue and turquoise. I then painted a paisly design on my clear cap. I sprinkled just a touch of baking powder randomly on the powder frit base. I then flipped the painted side of the clear cap face down on the fine powder frit and baking powder.
I should try this firing later this week when I’v made a few other projects to fill my kiln. I will keep you posted. I’m a little nervious about the firing schedule for this piece.
Cross your fingers.

Good luck, CDChilds. Perfectly formed bubbles are frustratingly elusive. Has anyone tried using translucent ceramic glaze? I saw something on Flickr.com that mentioned this. Small to med sized bubbles resulted. I wonder too if anyone has tried glass paint sprinkled w/ borax, b. soda or bubble powder. Or mixed with? I find that frits and enamels remain granular.July 28, 2014 at 7:32 pm #11314dgiambroneParticipant
I have had the best success using bubble power or baking soda diluted with water (heavily diluted at that) and then painted on and sandwiched in between layers of glass. I have added frit, enameling powders, ceramic underglazes, beads and more to add color. the best advice: make small practice tiles and see what works for you!August 20, 2014 at 3:33 am #11315wordanaParticipant
I have a few posts on my blog about experimenting with different methods for bubbles:
