Biscuit firing is 900 - 950 °C.
If it will not be glazed as a biscuit, it can be made in a single firing at 1200 °C.
If biscuit firing is done at a high temperature, problems will arise in glazed firing, as it will be difficult to keep a glaze.
Deformation will occur due to not keeping the secret, blackening of the glaze and the object's high degree for the second time.
When the firing color is glazed with a transparent glaze, the mud color turns out to be creamy.
It can be worked with underglaze paint.
It should be glazed with a transparent glaze.
If white is desired, it should be glazed with opaque glaze.
In the product glazed with opaque glaze, the under-glaze decor disappears.
Glaze Firing Temperature: 1180 - 1220 °C.  ( High Rank )
