Can I save this?

[Marsha]

I got a bubble!!   Can I save this??  I'm doing a child's handprint in the middle if I can ever get the hole out!!!

I dont have as much experience with a kiln as others here.  But the problems I had with bubbles were not repairable.

My guess is no.  BUT it is only my guess. You need to have someone with more knowledge address this question for you.   Sorry.

Is the bubble between 2 layers or not? If not, then why not try flipping it over, doing a complete fuse to flatten it out and then flipping back over and fire polishing it.

You have nothing to lose at this point.

Hmmmmm! I am not sure what I am looking at either. Is it a 3 inch bubble between two layers or did the bubble form under the glass. how are you doing the hand print once the glass is flat?

[Stephen Richard]

I suspect that we are looking at a single layer of glass with a border of frit.  If so this is a very good way to make a large bubble.  I may be wrong of course, but to continue with the thought.....
Not only does a single layer of glass begin to thicken at the edges as it rises in temperature and therefore trap air under the glass by the heavier/thicker edge causing the air to further expand and raise the glass in a bubble as the glass softens, but also the frit border increases the thickness of the edge in relation to the centre, emphasising the conditions for bubble formation.

If however the bubble is between layers, it indicates a more cautious bubble squeeze is needed.

But, we don't really know how the hand imprint is being done.  It is entirely possible that the imprint is causing the bubble.

More information on method please.

It is a double layer of glass...clear and white with the frit border. The bubble was very thin and I broke it easily...but then I had a DUH moment.  I thought  I would just put a round piece of white over it and  it would be ok......ha,ha,ha.  That just made another bubble.  I think I should have put the new glass on the bottom!!  I'll try the flipping and see what that does 'cause you are right...I have nothing to lose at this point!!!       I made the blank first for the hand print because I  saw a goober on the other one and I tried to hide it and the dang thing broke in five pieces because of another DUH. Of course it is going to break when you have the imprinted  hand which does not allow the plate to lay flat!!!!  DUH!!! I used fiber paper for the hand print but haven't done that part on this one yet.  Maybe I should just start over.....

[Stephen Richard]

Have you fired the fibre paper to remove the binders and the resulting gasses before putting the glass over it?

[ct4mom]

Marsha, I did the handprint thing for my grandkids last year and have so much glass to make into frit, I tried to use the method in the free spectrum site... I finally traced the handprints on fiber paper and laid my glass piece over it and worked great . I even left them flat put on rubber feet and they display them on an easel and use the for their birthday cakes.

Thanks everyone!!  Stephen, I didn't know you had to do that with the paper.  I'll give it a try!
