Tableware / Porcelain


Porcelain bodies are produced using a mixture of clays, kaolins, fluxes and quartz.

Porcelain are classified in 3 categories:

  • Hard porcelain: Firing temperature  : 1400 ° C
  • Soft porcelain: firing temperature 1250 ° C
  • Bone china: Firing temperature : 1280 ° C

The quality and consistency of the raw materials used for procelain production influence the main properties of the ceramic body such as:

  • Vitrification (Nepheline, Clay, Kaolin, Feldspar, Wollastonite)
  • Strength – fired and unfired (clay, kaolin)
  • Fired Shrinkage (Feldspar, all)
  • Dimensional stability (feldspar, kaolin)
  • Fired Colour :Low level colourant oxides leading to excellent fired whiteness (kaolin)
  • Chemistry (all)
  • Plasticity (clay)
  • Low permeability
  • Hardness
  • Toughness
  • Translucency and resonance combined with high resistance to chemical attack.
  • Consistency (all)
  • Particle Size

Porcelain is decorated with glaze influencing the aesthetic effect of the porcelain surface. For more information on Glazes, please go to the Frits & Glazes section of this tool.
