Raw Materials for Porcelain Production






Porcelain - white gold. We utilize it day by day, judge it by its form, colour, design and decal yet there is so much more to know about this material. Porcelain is one of the most ancient materials, which were discovered by human. Its discovery was around 10,000 bc. Wether it was porcelain or pots consisting of "fine earth" is not clear. For judging this a detailed analysis of raw materials and burning temperatures is essential, which we will offer on this page.













Porcelain usually consists of two different elements: 

  • hard burned porcelain mass (body)
  • the with batch covered protection layer (glaze).



This part "raw materials" is about the compostition of the body of the porcelain.







the raw materials of the body 


Porcelain belongs to clay mineral containable ceramics. To unterstand the composition and effects if this differenct minerals, a lesson in chemistry is necessary. We will explain you the essential characteristics of material knowedge of the porcelain-industry.  In general porcelain, in its original production consists of 50% porcelain soil (kaolin), 25% quartz (Siliciumdioxyd SiO2) and 25% feldspar.

binding material & melting catalyst



1.150 - 1.250 °C


Each of these components serves important functions in the production. A rule is - the more quality the raw materials have, the more these raw materials have been picked and processed, the better is the quality of the porcelain. When it comes to the availability and quality of raw materials Germany has a main advantage in Europe; we have a good deposit in the Oberpfalz, in Böhmen and Thüringen.  


The modern porcelain-production does not only work with just three components today. The increasing technical improvement and the production and improvement of minerals and additives makes it possible to optimize mass production. Also mixing raw materials makes a difference in melting point and compotistion of the mass. Our graphic on top shows 16 different raw materials in a factory which produces hard porcelain. Let's compare it to beer; everyone know beer consists of water, hop, malt and original gravity but still every brand tastes different.


The melting point of each mineral has a great impact on the hardness of the dish.
