What did Eggshell Porcelain look like?

Extremely thin porcelain body (as thin as 0.5-1mm), translucent against light. Regular in form with a smooth, lustrous glaze.

How did Eggshell Porcelain work?

High-purity porcelain clay → fine elutriation → thrown to extreme thinness → refined trimming → bisque-fired for strengthening → glazed → high-temperature firing → shrinkage rate controlled throughout the process.

Eggshell Porcelain

Eggshell-thin porcelain body — thin as paper, translucent when held to light. Requires precise calculation of drying and firing shrinkage rates to prevent deformation and cracking.

Scientific Principle

Ceramic shrinkage calculation: drying shrinkage (~5-8%) + firing shrinkage (~10-15%). Precise matching of dimensional changes across different stages.
