To make a long story short, I had to have one of my dogs' put to sleep and cremated. The cremation service sent me an un-baked clay medallion with my dog's name on it and his paw print. This was a total surprise to me! Anyway it came with instructions. It is un-baked and I do not know what type of clay it is, but it says to bake in conventional or toaster oven at 275 degrees on a GLASS baking dish. First of all I have never seen a glass dish for use with a toaster oven. I do have Pyrex but they will not fit into my toaster oven and my Pyrex pie plate is the only one almost flat enough to put in a conventional oven with the clay piece in the center. I was planning on using the toaster oven for the purpose of convenience, but the flat Pyrex glass pieces I have seen at Wal-Mart say not to use in toaster ovens. The clay instructions also state not to use metal.

Any suggestions for me?
