Advice /

The slower you fire the SUPERMANGA, the less fumes (organic matter) you will have and the better you will get.

From 1100°C onwards, the temperature should rise slowly so that the oxygen can still pass through the still porous surface. If you climb too fast, you will get blisters or bursts or slits.

No bearing at the end of firing to avoid any softening of the clay.

Firing in a reducing atmosphere with precautions.

When you reach 1100°C, slow down the rising in temperature.

For an excellent effect, fire very slowly.

Blue effects in reduction.

Ventilate the room well during firing.
