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.
