Holding a white ceramic coffee cup in your hand, have you wondered how ceramics are made? Today I’m going to tell you step by step process just for you to have rough pictures of how we do in our factory.
- Shape the clay into the shape we want. In this step, we can do it by hand. However, in mass production, we usually use plaster mold, roller, and jigger. After finishing the body, let the clay dry before finishing.
Finishing - clean and make the surface of the body smooth
TIPS: Always stir the glaze every time before you dip because the glaze may cause rough surface later after firing.
5. Put the glazed items in the firing again. This time we do 1,230-1,260 degree Celcius. We have to control the temperature in the kiln well so that every pieces in the kiln will be well done.
The ceramics are now well baked. We have to let them cool down in the kiln a bit before we can take them out.
The cone is used to tell the temperature in the kiln. If it comes down nicely like in the picture, it means the temperature is controlled well and the ceramics are well-done.
