What is the unglazed temperature of porcelain clay?
Hello, this is Fuchino.
We recommend 900℃ as the temperature for unglazed porcelain clay.
In the case of porcelain clay, unglazed at 800 degrees Celsius, it has low strength and is weak and brittle.
There is a greater chance of damaging it when handling it for painting or glazing.
However, the fact that it is unglazed at 800℃ does not mean that the color of the main firing will not change.
However, unglazing at 800℃ does not change the color of the main firing.
The result of unglazing at 800℃ or 900℃ will be the same.
The difference between unglazed at 800℃ and 900℃ is the strength and water absorption rate of the unglazed state.
The difference between unglazing at 800℃ and 900℃ is the strength and water absorption.
In terms of ease of handling after unglazing, we recommend unglazing at 900℃.
If the kiln is set up properly, unglazed porcelain clay should be fired at 900℃.
If the unglazed clay is too brittle at 800℃, or even if it is fired at 900℃, it is better to change the firing kiln.
In such a case, the temperature inside the kiln may be lower than the thermometer.
In this case, increase the temperature setting.
