Question: what is the difference between vitreous china and porcelain?
Answer: 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 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).
