Somebody asked this same question a while ago, also including 'pottery' in the mix. Setting aside the technicalities, in everyday English it's a question of how fine or delicate the finished product is. Going from the coarsest to the most delicate the order is: 1. pottery 2. china 3. porcelain

China and porcelain use different techniques in manufacturing, but basically they are the same thing. They are both ceramics.

Here is a professional answer for you I have found and thank for your smart question, so I would rather choose porcelain. http://knowledgenuts.com/2013/12/27/difference-between-fine-china-bone-china-and-porcelain/
