they will drip and they will burn out the color because the kiln is to hot you will have to fire the pot then lay in your glass and fire at a lower temp. sp
I don't know if you have fired your pot yet, but I have used glass that I used wood glue to affix to the pot while greenware. When I fired to bisque they melted and ran down the pot. My glaze firing was by Raku firing and the glass ran more. The object was a stoneware bottle and the glass started on the sloped shoulder of the bottle. My guess is that it will run off the pot, but enough residual will be left to stay in your original position. Depending on how it runs it may be cool. Good luck.
you could try putting a rail of clay across the glass tiles, like a top and bottom frame to keep them from popping off. you'd have to make it loose against the tiles for shrinkage, but still attached well enough to the vessel that they wouldn't come of themselves.
Third is with the glaze fire, again with shrinkage rates, but also at this point the glass could run completely off, or react with whatever glaze you use and run. It will most certainly crack/craze, and depending on your temp, (I'm assuming cone 5/6) yellow reds pinks may change or wash out (green and blue are most stable)
We've used crushed glass, marbles, bits of glass frit (glass slumping stuff) with interesting results, but on the horizontal.
You'll have three points of challenge, because of coefficient of expansion - the rate at which a substance expands and contracts with temperature. your first challenge arises going from green to bone - the clay will shrink, the glass will not, and may pop out ( in horizontal application this is not an issue - it may still pop them but they dont go anywhere)
second point is the bisque, for the same reason. if they stay in, they may crack from the stress depending on the temp.
I dont know if the shrinkage of the green to bone is actually described as a CoE event, but it is a challenge, and CoE is different for different types of glass, so were you to buy some other glass product it may behave somewhat differently (but still craze when fired with the clay)
I use broken glass in with some of my paintings. This is a cool idea, but I too wonder what will happen. After you fire it, are you going to leave it unglazed or glaze it? Won't the glaze run over the glass? I want to see this when it is done. I want to see what happens!!!!
I don't really have much experience with this, so it's going to be trial and error. I would imagine I will get different effects if I low fire or high fire. mb
I really don't know anything about using glass, obviously. I know more now than when I made this video, however!

how did this turn out after being fired?

This is beguiling :) can't wait to see it.

I like this look :) I hope it works out but I have a suspicion that those glass blocks will pop off.
You've got alot of fun ideas, I really look forward to your videos!

Yes, That is what the general concensis is telling me. We will just have to see what happens! It probably won't work, and I'll have to go to plan B.

Looking forward to your results - keep us posted!

Rapidac emailed me the bascially the same concerns you're mentioning here. I didn't even think about shrikage rates, and etc.
I have no idea what's going to happen, but it's probably not going to work. I will keep you up to date, however. mb
