You can break them onto small pieces and use them like mosaic tiles for a number of projects. You can also draw on them with glass markers (hand prints, silhouettes, paw prints, etc) for gifts.
Oh, wow I am a collector of china. First I would display in a beautiful display Pinterest has lots of examples. I have also done the mosaic thing, a table top, an antique shoe form, a plastic head and a plastic figure of a woman. I have decoupaged numerous glass plates. Can you post a pic of the plates for more ideas?
I like the scenic ones as wall decor.
