If you notice a few tiny black dots on the surface of your Ou kiln celadon tea cup, please don’t worry — this is not a defect, but a 👉natural and normal result of traditional high-temperature firing in artisan celadon pottery.
Where do these black dots come from?
Every handmade celadon teacup is crafted from natural mineral clay, which contains trace amounts of iron. Although the iron content is very low, it is never completely zero when working with raw, unrefined 👉Chinese celadon pottery materials.
During firing at temperatures of approximately 1250–1300°C, small amounts of iron within the celadon glaze pottery may migrate and react. As the piece cools, a tiny portion of these mineral particles can appear on the surface as fine, scattered black dots. This process is:
-
Natural and Random
-
Impossible to fully control or replicate
-
A hallmark of traditional chinese celadon teaware
It is a core characteristic of handmade ceramic art, distinguishing it from industrial mass production.
Is this considered a flaw in collectible celadon ceramics?
No. In the world of museum quality celadon, these marks are often described as natural “kiln marks.” They do not affect the safety, durability, or the taste of tea when using your 👉gongfu tea set.
Instead, they reflect the reality that each celadon porcelain cup has gone through an authentic firing process. Much like a 👉vintage Chinese teapot, no two pieces are ever exactly the same, making your cup a unique piece of celadon art pottery.
Our Quality Control Standards Before shipping any premium celadon tea cup, every piece is carefully inspected by hand:
-
Pieces with excessive impurities or visually distracting marks are rejected.
-
Only items that meet our strict aesthetic standards for 👉traditional celadon teaware are approved.
That said, due to the nature of handmade teapots and cups, a very small number of pieces may still show subtle dots. This is considered acceptable and normal within Ou Kiln celadon craftsmanship.

-
👉Free exchange (subject to availability)
Our Philosophy The beauty of celadon ceramic tea cups does not come from artificial perfection. It comes from the dialogue between earth, fire, and glaze. These subtle traces are evidence of authenticity and the traditional chinese celadon teaware process behind every piece.
