Vitreous china is a glazing technique that is added to porcelain. It is a glass based enamel coating that makes things more durable, denser, and shinier. When a large amount of heat is applied to powdered glass, a liquid called vitreous enamel is created.
The term “Vitreous China” refers to ceramic materials (like porcelain) that have been glazed with vitreous enamel AND can also be used to refer to the actual enamel coating. When shopping, they’re essentially the same thing but if you want to get technical, they are different; base (porcelain/ceramic) vs the coating (vitreous enamel). No need to make things overly complicated.
