Chinese Porcelain Marks: Reign Marks, Hall Marks and Copies
Understand Chinese porcelain marks: six-character reign marks, seal script, hall marks, apocryphal marks and Republic period marks, and how to read them.

Chinese porcelain marks are fascinating — and famously unreliable on their own. Understanding the main types helps you avoid the classic mistake of dating a piece by its mark alone.
Reign marks
The best-known marks name an emperor's reign, typically in six characters arranged in two or three columns (or four characters). They read roughly: "Made in the [reign name] period of the Great [dynasty]".
Reign marks appear in:
- Regular script (kaishu): standard written characters
- Seal script (zhuanshu): more angular, archaic characters, often in a square
Apocryphal marks
Potters often used the marks of earlier, admired reigns on later pieces — as homage, to signal quality, or to deceive. These are called apocryphal marks. A mark naming an earlier emperor is extremely common on later and modern porcelain.
Hall marks
Some pieces carry "hall marks" naming a studio, pavilion or residence rather than a reign. These can relate to particular workshops or owners.
Symbol marks
Instead of characters, some pieces carry symbols — leaves, fungus, objects — especially on certain export or kiln wares.
Republic period and later marks
Early 20th century pieces may carry marks referencing the Republic period. Some later pieces bear "China" or "Made in China", indicating export markets in the 20th century.
How experts use marks
Experts read the mark as one clue and compare it with:
- The style and calligraphy of the mark itself (genuine period marks have characteristic brushwork)
- The body, glaze and foot of the piece
- The painting style and cobalt
- Form and decoration typical of the period
If these don't match the mark's claimed period, the mark is apocryphal.

A mark of an earlier reign used on a later piece.
What does seal script mean?
An archaic, angular style of Chinese characters used in some marks, often in a square format.
