This came from the estate of a friend's family. The mother is in her 70s and inherited this from her mother. It clearly no longer holds liquid, but I'd hazard a guess that it would have held around 4 ounces. Aside from residing in Northeast Wisconsin for the past 50 years, it's home was in Northern Wisconsin. Prior to that, we're uncertain. Due to it's age and brittleness, I won't make any attempt to clean it.
