Is carnival glass safe for serving food?
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...  ;-)
