I have a very pretty wine glass, a gift from my son and DIL a couple Christmases ago. Unfortunately it took a dive yesterday and the stem broke. Does anyone know of a product I could use to fix it? I have the major pieces of the stem, only missing a couple of chips. I am thinking of a Sculpey or Fimo-like substance, but more like ceramic as I think polymer clay is too flexible to work well. Also something that works in a home oven if it needs to be baked.
