In this article, we’ll walk you through the evolution of Chinese Pottery and discover some of the most valuable pottery marks you should pay attention to. Continue reading if you are eager to expand your knowledge.

How Different Marks Determine The Value Of Old Pottery?

It is crucial that you know how certain potters, potteries, and patterns are highly valuable among collectors. The incised pottery mark can tell you whether or not your item is less or more valuable. 

Moreover, pottery marks in some cases contain a date or a sequence of numbers that enables you to determine the age. A general rule is that the older your pottery is the more value it has compared to newer ones.

Types of pottery determined by materials used

Pottery in general is categorized by the type of material it was used for making, as well as geographical location – we have pottery that originates from the North and South.

The first lesson is – Chinese pottery marks are classified based on the materials used for crafting! Remember this! Here is the list of the most common materials used:

  • Earthware – Before the Chinese discovered porcelain they used more common and available materials such as earth clay. To form earthware of the porous earth clay makers exposed their handcrafts to 1200 Celsius to make it keep the shape intact. This practice has existed since the Neolithic age.
  • Stoneware – Since earth materials were too porous, artisans started looking for more durable materials. This is how the Neolithic Age evolved to the Stone Age. To form a shape from clay that was tighter than earth clay they fired their handcrafts on 1300 degrees Celsius.
  • Bronzeware – Bronze is an alloy made of red copper and other elements like lead and tin. In ancient China, artisans called it “Jin” or “Ji Jin”. Keep in mind that bronzeware is golden when it is cast. The reason why it is called bronze is because it turns green when it is unearthed. This is due to the oxidation and rusting that occurs with time.
  • Porcelain – 3,000 years ago, the Chinese discovered a combination of vitrified ceramics and fine clay that became porcelain after it was exposed to high heat. Since artisans were eager to mark their art with indications of production dates so they could keep track of history this material was perfect for it.
  • Shang Dynasty Pottery – The first record of Chinese Pottery was the Shang Dynasty Pottery which was made sometime between 1600 to 1046 B.C. A thousand years after that, which is the period between 25-220 A.D. the Eastern Han Dynasty produced the first ever Porcelain.
  • Tang Dynasty Pottery –  Between 618 and 907 A.D. the Tang Dynasty promoted tea which led to the popularization of tea sets made from Porcelain and Ceramic. This was when a tricolor Sancai, five-color Wucai, and exotic Qingci from Hebei and Hunan were discovered.
  • Jingdezhen Pottery –  Soon after Jingdezhen became the Porcelain capital of the world. In this period the West and East were united through trade, thereby their different styles started combining. Emperor Zhenzong (997-1022) was very interested in Porcelain and popularized it amongst royals. The royal dynasties invested in the production of Porcelain, one of the famous were the Ming Dynasty (1368-1644) and Qing Dynasty (1644-1911). They produced the highest quality Porcelain wares ever.

However, not only antique Chinese pottery and marks are valuable nowadays. There are plenty of new-age pottery masters and artists who manufactured pottery items worth a lot of money. We will mention a few of them in the following section.

Determining The Worth Of Your Pottery

Determining the value of an old pottery isn’t easy. But, there are a few factors you can take into consideration when trying to figure out how valuable your item is.

  • Condition – The worth of a piece of pottery is directly linked to the condition. When something is in pristine condition also known as “mint” condition it will cost much more. There should be no cracks, chips, or breaks. The perfect means it stayed in the same condition as when it was first purchased. Damage, regardless of how minor it is will significantly lower the price.
  • Rare style – Rare and uncommon items are the golden grail in the collector’s dictionary.  This indicated that there are only a few examples like yours, or maybe even none. Such fine pottery is very expensive! We talk about hundreds of thousands or even millions of dollars! Especially for pottery such as vases, plates made of porcelain, and stemware made of crystal. Also, by rare we also mean odd patterns, glaze, colors, sizes, and forms. 
  • Originality – Originality in terms is the complete idea and realization work of an artist or he was inspired by another’s work and reproduced some ideas. This might sound funny to you, but in the world of art being authentic and original is what counts and what sells!
  • Aesthetic value – This is often subjective because what is pretty to me does not need to be pretty to you. However, pottery items often have universal aesthetic appeal, which will command a very high price. When something is attractive to most people it grows in value.
  • Provenance – Provenance is a documented history of the item’s previous owners. If the particular pottery was owned by some famous people or historically important person the price will jump significantly. So knowing the brief history of a piece of pottery you are interested in will greatly help you.
