Whichever way you call it, these fashionable utensils of the first 7 or 8 decades of the previous century are getting less popular by the day.
They were favoured for their relatively light weight, though the base material was ordinary steel sheetmetal. The enamel coating imparted a decent degree of resistance to wear, and corrosion. And it came in all sorts of colours, and often with flowery decorations too.
However, the coating was vulnerable to knocks, which caused chipping and flaking, leaving ugly spots and patches, which led to corrosion. After prolonged use, the insides of the utensils could get stained too.
