Porcelain pulp is made from thin mixtures of kaolin, quartz, feldspar and other aluminosilicates and includes up to 40 different additives.
All ingredients must be blended in strict proportions.
Below is short description of some main processes:
1. Filling a hollow plaster mold with a porcelain mass (open casting process)
4. 1st Firing at a temperature of 700-900 degrees Celsius in a special kiln for firing ceramics.
6. 2nd Firing at a temperature of from 1100 to 1300 degrees Celsius
7. Applying the paint and logo
8. 3rd Firing in a kiln (smaller in size) for firing, at a low temperature
Actually, here could be even 4th Firing, it depends on colours pallette. ;-)
9. Quality test is a process of the careful selection of quality, and in case the product fully complies with our intern standards, we send them to the final assembly.
10. Final assembly
