Is the enamel finish on modern Agas the same as on older models?
No, it isn’t. In the 1940s they used a cooler enamelling process which gave a better and harder finish, but it was harder to get consistent results, so they moved over to the newer finishing process. So the enamel on the old Standard Model CB, for instance, was harder and probably better quality than what is used today. Index Contributed by: Richard Maggs (The Aga Advantage).
