Excuse me: What are these two pieces of porcelain? Is it collectible?

First of all, I'm sure that the two things you are wearing are old. The first one was left over from the Yuan Dynasty, according to the shape of the implements. It was a lip jar during Chenghua period in late Yuan Dynasty and Ming Dynasty. The joint mark in the middle also revealed his age and identity. It is white glaze, which can also be called sweet white!

The second one is the blue-and-white sunflower dragon bowl in the early years of Yongzheng-Qianlong. Look at the third generation goods when repairing!

The first one starts at 3000, and the second one starts at around 2000, which is worth collecting!
