What are posh porcelain tea sets called china sets?

While "china" is often used to refer to porcelain tea sets, it's not technically correct.

Here's why:

* China refers to the country of origin, not the material.

* Porcelain is the type of ceramic material used to make fine tea sets.

So, while "china set" is commonly understood, it's more accurate to say "porcelain tea set" or "fine bone china tea set" (if the set is made of fine bone china, a type of high-quality porcelain).

You can also use other terms like:

* Tea service

* Tea set

* Dinnerware set

Ultimately, the term you choose will depend on the context and your personal preference.
