Is carnival glass safe for serving food? 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.)
Don't use any food containing:


alcohol
acids (lemon juice, vinegar, ...)
oils (butter, mayonnaise, cream, ...)


So a salad without oil&amp;vinegar should be safe for daily use, but ice cream, punch, pie (contains butter) etc are to be avoided.  The health effects should be minimal, but you'll definitely ruin granny's beautiful set in the long run...  ;-)
