Eggshell Porcelain
Eggshell porcelain achieves walls so thin they become translucent. Named for their eggshell-like delicacy, these wares represent the extreme of ceramic thinness. The technique requires extraordinary skill in throwing, trimming, and handling.
Technical Achievement
Creating eggshell porcelain involves throwing extremely thin walls, then carefully trimming to uniform thickness. The slightest pressure can collapse the walls during production. Success rates are low, making surviving pieces rare and valuable.
Light passing through the translucent walls creates ethereal effects. Decorators often painted designs to be viewed against transmitted light, creating double images.
Historical Production
Yongle period imperial wares established the eggshell standard that subsequent periods attempted to match. Qing dynasty revival achieved comparable thinness with more consistent success. Export markets particularly valued these demonstrations of technical mastery.
Contemporary production continues the tradition, though genuine antique eggshell commands premium prices. The fragility that makes these pieces remarkable also makes survival to the present remarkable.
