Firing ceramics
Depending on the firing process, firing is usually carried out at a temperature of 900 to 1240 °C. The positioning of the firing parts is important, as they need sufficient distance so that they do not touch each other and the temperature distribution is optimal. It has also proven to be advantageous to first slowly increase the temperature to 600°C in order to then reach the maximum temperature. If you pay attention to this and allow the product to cool down completely between firings and dry completely, you should have no problems with spalling thanks to the even temperature of our kilns.
The firing process in 3 steps
- Immediately after the clay has dried, the first firing can take place at around 900 degrees Celsius, which ensures the strength of the clay. Bear in mind that the material loses up to 10% of its mass and take this into account in advance.
- You can glaze the product after firing.
- Ensure that the material has cooled down completely before the last firing. The temperature depends on the glaze and is usually between 1020°C and 1240°C.
Are you looking for a pottery kiln or a kiln for industrial ceramics?
Would you like to load and operate the kiln from the front as a front loader, from above as a top loader or for large or many products as a shuttle kiln or bell kiln?

How big should a kiln be?
As a rule, the correct kiln size is defined by the quantity or size of the material to be fired in the kiln. It is essential to ensure that a sufficient distance to the heating coils is maintained. In principle, no more than 80% of the volume of a kiln chamber should be used in order to give the heat the space it needs for optimum firing results. Whether your new kiln will ultimately be a front loader, top loader, bogie hearth kiln or hood kiln depends on various factors – not least the available budget. We will be happy to provide you with expert advice to help you make the right decision.
What maximum temperature should a kiln have? And what type of heating should I choose?
In ceramic firing, a distinction is usually made between biscuit firing (usually < 1000 °C) and glaze firing (usually > 1100 °C). Normally, kilns for ceramics and porcelain with a maximum temperature of 1320 °C are absolutely sufficient; high-temperature kilns (> 1400 °C) are only required for firing special ceramics. The permanent working temperature of a kiln should not be more than approx. 100 °C below the maximum possible kiln temperature in order to limit wear on the heating elements and the kiln as a whole. Whether a kiln should be heated with electricity or gas depends primarily on the size of the kiln, the energy costs and the space available.
