Oh, Source of All Knowledge!

I am creating something which will have Fimo polymer clay along the edge of a mirror.



Question: if I put the mirror in the oven with the Fimo, will the heat break the mirror?



In other words, am I better off curing the Fimo separately and then hot-gluing it to the mirror?



I'd really rather fold the Fimo around the back of the mirror if that will be possible.


If you heat it very slowly and then cool it very slowly, it may be OK. But I guarantee if you heat it quickly or stick it in a hot oven, or get it hot and then cool it quickly, you will have glass confetti. And I own a hot glass studio!

Thanks, Pat! I knew glass could take the low temperature at which you cure Fimo, but wasn't sure if the mirror-coating would change that.

Karen C - California had some very interesting things to say about Oh, Source of All Knowledge!:

Hmmm, wondering what the mirror is made of......

Polymer clay takes low enough temperatures for a short enough period (15 minutes per 1/4" of thickness, usually) that I'm leaning toward "probably safe". Of course, with your oven being so inventive about temperature control...... :-)
