Mark C. Posted November 13, 2020 Report Share Posted November 13, 2020 Marilou, Boil the pot with glass and then put in freezer or vice vera. If it can take that its a keeper-keys in the bowl is not a striong enough test. Link to comment Share on other sites More sharing options...
Min Posted November 13, 2020 Author Report Share Posted November 13, 2020 7 hours ago, Marilou said: I use Bullseye COE 90 very fine grained frit to good result — not on the interior of functional pieces, but wedged into clay, or pooled onto shoulders and edges and on the exterior of pieces. In test I have done several bowls with glass pooled in the bottom just to test durability — so far even with keys and other items tossed into these bowls, I have no breakage, no shards, no splinters and no blood . If there is even the slightest chance of the pot being used for food by someone, in addition to more stringent physical testing you might want to consider getting the pot tested for lead and or cadmium release. From Bullseye there are 51 of their colours that contain more than 1% lead and 47 that more than 0.5% cadmium. COE of glass is multiple times the COE of any claybody, as much as we would like, we can't get away from the laws of physics / thermodynamics. Welcome to the forum.

blackthorn Posted November 13, 2020 Report Share Posted November 13, 2020 @marilou I'm right there with you on combining ceramics with other disciplines. My interest is combining photography onto ceramics. Of course, there are a good handful of folk who have come up with some successful methods on this front. It does take persistence and testing. I applaud your pursuit. I have not much interest in creating functional ware but always enjoy looking at it. Many here excel at that with centuries worth of experience and wonderful examples to show for it. Perhaps when you find a spare moment you can post some images of your work. I imaging I'm not alone in wanting to see what you share. Link to comment Share on other sites More sharing options...
Mark C. Posted November 13, 2020 Report Share Posted November 13, 2020 I have never seen a glass fuzed to ceramic piece that would be functional and safe. Mug plate etc. Key bowl well thats fine until someone puts cereal in it. Bullseye as moted above has some nasty stuff in much of the products that make it unsafe for food functionality.Great for sculpture I'm sure-yard art as well.Flower pots ok.

Chilly Posted November 14, 2020 Report Share Posted November 14, 2020 Don't mix materials that are not designed to be fired together. It's an accident waiting to happen. There are enough questions here about clay and glaze not fitting together. Link to comment Share on other sites More sharing options...
JohnnyK Posted November 14, 2020 Report Share Posted November 14, 2020 Sometimes there's art just for the sake of art...in this image the bottom of the sculpture incorporates a pool of glass and there is some glass in the small bowl on the left...

Callie Beller Diesel Posted May 24, 2021 Report Share Posted May 24, 2021 That’s a really cool page! One point I notice, and that the author is also quick to point out, is that incorporating glass cullet into the clay body matrix is different than firing it as a separate layer on top of the piece, because of how mesh size affects melt. At a 50/50 mix of clay and 12 mesh glass grog, it’s the clay particles that wind up acting like aggregate in concrete. Given that the above website is fro 2007, I wanted to see if any of these products had potentially made it to market. I did find a company that goes one step farther, and uses repurposed aggregate from demolished buildings instead of clay. They’re in New York State.
