Curiosity Question In Regards To Using Glass In Claywork


Recommended Posts

I have used glass in some of my works in the past and truly enjoy the look of it. I rarely use this decoration because it was my understanding that any piece created with glass being melted and fused to the clay body was not food safe. I have seen other potters that use this process and it is being sold as being ok for food. 

 

Did I understand incorrectly or is there some way to utilize glass in some way that actually does render the surface that would come in contact with food safe for consumption?

 

Thanks y'all!

I've used glass melted into recesses in porcelain pieces, but I would not use the technique on surfaces that might come in contact with food.  There are a couple of reasons for this.  One is that you don't really know what is in the glass you might be using.  The other reason is that the expansion co-efficients are so different between glass and clay that the glass will craze wildly, and these cracks could cause problems with food residue, and in some cases, bits of glass breaking loose.

That's what I thought. I may reach out to them to let them know, I would hate for someone to get sued over something like that. I couldn't imagine how it could be made food safe but then I certainly don't know everything!! lol Thanks for the responses. :-)

DebI:

Check with some glass art suppliers: I know there are some products used for food. Some are, many are not: so it would require research to ensure you are not introducing non rated products. Then you also get to deal with COE issues as well :).
