Blue porcelain or blue pottery is a national treasure of the Netherlands. It is made in imitation of Chinese porcelain. You can see the whole process of blue pottery production in the blue pottery factory, and there are Chinese guides. There are painters painting blue pottery on the spot, and there are many blue pottery treasures. The price of blue pottery products in the store behind is very expensive, and any small piece costs hundreds of euros. There are also some so-called discounted products, which cost dozens of euros. They are shoddy and not recommended to buy.
