My grandmother-in-law left us a very large collection of carnival glass. This has led to a mild debate over whether it is safe to use.
Are there foods that shouldn't be served on carnival glass? What are possible risks of occasionally using the dishes for (e.g.) ice cream, pie, or a salad?
(The "unsafe" vote also points out that "it's an expensive antique and needs handwashing, why not just leave it in the cupboard?" which may make the safety issue moot, anyway.)
