fusing ceramics and glass via glaze

[frillcappa]

Would it be possible to use a glazed piece of ceramic and fuze it to boro? anyone ever try putting ceramic glaze on boro, or any type of glass and bake it in? any special type of glaze that is made for glass? If you have any Ideas feel free to chime in. thanks

i doubt it could work with boro, maybe a chance with soft glass,../? no idea really , the only way I can see it possibly working is dipping more than half a marble in glaze then sticking it to a ceramic pc w more glaze, so the glaze is more holding the marble than actually using it as adhesive.? .....sounds possible

when i was at a community craft center in California this week i saw a lady who was teaching a class on bake on glass to metal. she made a sweet detailed cat then inset it into a nice sterling silver pendant. they sifted very very fine powder into pics on copper, most likely a form of soft glass, not boro for sure.. the copper first had to be completely free of moisture, they would bake the peice first to achieve this. the through a series of layers for the picture they went under very hot heat lamps to bake the glass hard and to the surface of the copper. then they could glaze over it making it nice and shiny and smooth.
dont know much about it but it was pretty cool and the teacher made some very very impressive pictures out of the fine colored silicate.
im many ways im sure this is fairly relevant to baking glass and pottery together. when i read this post it made me remember the process and how cool the teacher was to take time and explain it to me.

not sure on using glazes to join the two mediums, but i watched a company experiment with ceramic glazes from their ceramics dept. onto their glass pieces.

they used some opalescence kind of glaze, rainbow colors. it was kind of a very subtle effect. reminded me of some old "carnival glass" with those iridescent qualities.

not sure it did anything to make their production glass look any better and they pretty much scrapped the project, but it might be cool affect for artsier works.

there are probably glazes that fire as specific temps that would work well with boro, or maybe there aren't but can be invested with powdered glasses to create something that could be fired on.

Make your own glaze with powdered boro and water?

IT can be done
But its going to take a lot of work I have been wondering aboult this for a while now...
I think its totally possible but its ggoing to be a real pain in the ass to get a goood result.
Clay is like glass you use certain clays with certain glazes and so you just have to find the right body to match your glaze.
Glaze is not just glass
it is usually made to match the clay you are working with but i think you could say take a
boro fritt and some clay and watter mabie some ashes
and try it out i asked my ceramics professor and he told me i could try it all i want in my own kiln ..... so you might want to put your test tiles on a try
I would love to talk more aboult it and even try some my self as i have been literally been asking myself this same question for the last 8 months
glaze = alumi+ Silica+flux most of the time
al=keeps graze on pot
Si=makes glass
Flux=makes glass melt
hope this helps Im in for the experimentation

Boyce Lundstrom wrote some books on the topic of "bridging" glass. Check 'em out.

And that whole glass on metal thing is enameling. You can get everything you need for that online.

All good points man...This was actually my brothers Idea, Hes used to be into ceramics, and we were talking about glass, and he came up with this idea. I need to get my hands on some different glazes and clay to try it out.

Ok im in ceramics at my school right now. Recently I took 2 glazed bowls that had cracked in the kiln and laid a bunch of soft glass stringers over the top. I also got another UNglazed bowl and filled the bottom with boro frit. The kiln I was using was a paragon slumping kill, 1700 F max. I took the kiln to its max temp and then dropped it. Long story short....the soft glass did fuze itself to the glaze but there are a ton of little stress fractures all over the glass. Im almost positive that the ceramics and the glass expand at different rates. As the kiln was coolin from 1700 I heard a million little "ping ping pink ping" noises coming from the kiln, which was probably the glass cracking

On the boro side, 1700*F was not enough to fulling fuse the boro. It did sorta hold together but just barely. I think I could grab the form and smash it in my hand. I will be trying this again in the near future and if you want some pics of what I made so far send me a PM and a link to this thread and ill get some pics on tuesday in class.

oh and the clay i used was stoneware clay, fired to 2350* in a gas kiln. The unglazed stuff was the same, but only bisque fired to i think 1900. I am playing with the idea of making some molds and filling the with boro frit and then putting the mold in one of the regular ceramic kilns and taking it to a higher temp. I will take pics of anything I make in the future.

so heres a few pics of my experiment.

sweet man, thats a good result I would say... keep at it dude, ur onto somthing. +rep

[ReLo442]

Yea i plan on doing quite a few more but on the next one i will prolly use a sheet of glass large enough to cover the whole bowl. I have a few ideas that I may try out but i gotta do all this quick cuz the semester is over the first week of may and im not doing summer school. I need to do a few more tests with the glass to find out exactly when it slumps because Im thinking I may run into a problem of the glass pooling in the bottom of the bowl and I dont really want that. If I have time ill look into some slumping books. thanks for the rep

[D. dino i ninjah]

are the cracks from the glass bieing pulled appart or from it pushing togeather ?
YOU can do it just gotta get the clay and the glass to match
If you are pooling and you dont want to be make a high alumia glaze under the glass thats pooling it might contorl the running
If the glass is pulling appart when it cracks add silica if its pushing togeather add alumia or mabie vice versa but you can contorl the problem my real guess is that your going to need to make a boro fritt based glaze that will match coe
or a soft glass fritt based glaze and then arange the stringers over the base kinda likea graded seal in scientific work
I must say you have actually gotten further than i have
I have just thought a lot aboult how to do i never actually got brave enough to just try and see.
respect
peace

[ReLo442]

you def put way more thought into it than me. Im not exactly sure how to be able to tell if they are from pulling apart of not. I am going to try some of my black boro frit on one of my next pieces just to see what happens. Tomoro will be my last day to put anything in the gas kiln so we will see if I make it in time.
