I have a 45 year old double bowl cast iron kitchen sink. I bought it new, but stored it about 15 years ago. There are no chips but the finish needs to be redone. I am assuming it is porcelain. It is white, perhaps it is ceramic???? I don't know how to determine what type of finish and then how to refinish it.
