Blue and White Chinese Porcelain: How to Identify It
Identify blue and white Chinese porcelain: reign marks, foot rims, glaze, painting style and export wares. Plus how to spot the many reproductions.

Chinese porcelain covers centuries of production, from imperial treasures to export wares made for Western markets and modern decorative copies. Blue and white pieces are the most familiar — and the most often misidentified.
The big caution: most marks don't mean what they say
Many Chinese pieces carry reign marks (six or four characters naming an emperor's reign). Potters frequently used earlier emperors' marks out of respect or for marketing, so a mark is not proof of date. Learn more in Chinese porcelain marks.
Look at the foot rim
Turn the piece over and examine the unglazed foot:
- Clay color and texture: fine, smooth body vs. coarse or chalky
- Finishing: how the foot was trimmed, and any grit or kiln marks
- Wear: genuine age shows natural, uneven wear on the contact points
Look at the glaze
Older glazes often have a soft, slightly uneven surface with small bubbles visible under magnification. Some modern copies look glassy and too perfect — though skilled reproductions exist.
Look at the painting
- Cobalt color: different periods and cobalt sources give different blues, from purplish to grayish, sometimes with darker "heaping and piling" spots.
- Brushwork: confident, fluid painting vs. stiff, hesitant lines.
- Motifs: dragons, landscapes, flowers and figures follow period conventions.
Export porcelain
Huge quantities were made for export to Europe and America in the 17th–19th centuries, including tableware with Western shapes, armorial services and "Canton" patterns. Export wares are collectible and often more affordable than imperial pieces.
Reproductions
Chinese porcelain is extensively reproduced, from honest decorative copies to deliberate fakes. Be especially cautious with pieces offered as imperial or "museum quality" at low prices.
When to get an expert
The Asian art market can be very valuable. If your piece shows signs of quality and age, consult an auction house specialist in Asian art before selling. See how to find an antique appraiser.
Start with a scan
Photograph the piece and its base in daylight and scan with AntiqueIQ for an identification, estimated era and value range. Use it to decide whether a specialist opinion is worthwhile. Related: antique vases value.
Frequently asked questions
Does a reign mark mean my porcelain is from that emperor's reign?
No. Marks were often copied from earlier periods. Body, glaze, painting and foot are more reliable clues.
How can I tell if Chinese porcelain is old?
Examine the foot rim, glaze, cobalt color and painting style, and look for natural wear. Experts compare all of these together.
Is Chinese export porcelain valuable?
It can be, especially quality pieces in good condition, though values vary widely.
