TL;DR: To choose quality porcelain, look for a translucent, resonant body with a smooth, even glaze and no visible flaws. Prioritize reputable makers, check the foot ring and weight, and confirm whether the piece is true hard-paste porcelain or a lower-fired imitation.
1. Know the Three Types
Hard-paste porcelain is fired above 1,400°C and is the most durable. Soft-paste and bone china are softer and more chip-prone. Ask the seller which type you are buying.

2. Check Translucency
Hold the piece to light. Quality porcelain glows softly; thick, opaque walls often signal earthenware or stoneware.
3. Listen for the Ring
Tap the rim lightly with a fingernail. A clear bell-like tone means a dense, well-fired body. A dull thud may indicate a crack.
4. Inspect the Glaze
Run your finger over the surface. It should feel glassy and even, with no pinholes, bubbles, or rough patches.
5. Examine the Foot Ring
Turn the piece over. The unglazed foot should be smooth and flat, with no sharp edges or grit.
6. Look for Flaws
Check under bright light for warping, crazing, or color bleeding. Minor factory marks are fine; cracks are not.
7. Weigh It
Good porcelain feels surprisingly light yet solid. Excessive weight can mean a thick, low-quality body.
8. Verify the Maker
Research backstamps. Well-known factories mark their work clearly; blurry or missing marks are a warning sign.
9. Test the Rim
A quality rim is thin but not sharp. Run a finger around it to feel for chips or unevenness.
10. Buy from Reputable Sellers
Choose dealers who offer returns and describe condition honestly. Avoid pressure to buy without inspection.
