Art Clay Silver and Glass
Some of you already know that my background is in polymer clay. I've
only recently entered the mesmerizing world of glass via a lampworking setup. That necessitated buying a kiln and well, it's all been downhill from there. Now I have Art Clay Silver (along with some pottery clay) and I want to use the silver clay and the glass together. I have the ACS 650 which is, from what I've read, compatible with glass. My questions are such: 1. Should I fuse a cabachon (or whatever I'm making with glass) first and then build around it with the ACS? It seems to me if I do this, even though the shrinkage rage is minimal with ACS that the ACS will crack at minimum while it's drying and likely while it's firing. 2. Can I make a setting out of the ACS first, fire it and when it cools add a pyramid of frit (much like for a paperweight) and then fire again letting the frit fuse and form to the setting? I know ACS can be fired multiple times and it seems to me this would be the best way to go. Any suggestions? Thanks tons in advance! BH |

Its Good to ask questions, however your best bet as your set up is so
specific to you is to run some trials yourself. that way you will get more accurate results faster than asking others who at best can only give you a general answer. As with any heat/ceramic process, if youve had any friends who do real pottery ie over 1000@C work you will hear that a lot of the time its in the lap of the gods. IE results will always be different despite keeping everything as identical as possible. |

I don't know much about clays, but I do know a little about glass. This much
I know about your quest. It all boils down to the coefficient of expansion. How much the glass/clay moves when heated and cooled. If the two mediums are not matched close enough, they won't stay together. There are many different types of glass to choose from. They all have different expansion rates. Randy Hansen SC Glass Tech.

Well, the clay I'm using (ACS 650) is compatible with soft glass I know.
I'm not sure about borasilicate. But it matters not since I'm using soft glass in this project. I do plan on trying it with stained glass scraps as well to see what I come up with.
