Ceramics burn themselves: That's how it works!

Creating and painting ceramics yourself is a creative hobby that produces many beautiful objects. Frequently the desire arises to burn the products themselves, but temperatures of more than 800 degrees Celsius are necessary for this. Are there alternative ovens that are not that expensive? And how does the burning of ceramics in a conventional clay kiln work?

Build an alternative oven for ceramics yourself

In rural areas, it is possible to build an alternative outdoor kiln for firing ceramics, some of which burns itself. To be noted are in any case all fire protection measures!

The kiln type is called "tipi" because of its shape, it consists of a chimney pipe, hare wire and many layers of colored newspaper in clay slips (thick porridge of dried clay residues). A fire is placed under the stove, which heats the interior slowly but steadily.

If the stove ignites itself, very high temperatures are produced, which are sufficient for firing the ceramic. It usually takes a few hours for the fire to go out completely. The fired ceramic works then show clear traces of fire.

Burning ceramics in the conventional oven

If you make many pieces of ceramic, it is worth buying your own pottery kiln. Little distillers should inquire at various art shops or conducting a local pottery class where a stove is available for shared use.

The first burning process always takes place without glaze, he calls himself "biscuit brandy". Here, the clay becomes the so-called "broken glass", a firmly fired figure. Let your clay dry for a few days before firing so that it contains as little moisture as possible.

  • In the case of biscuit firing, the objects may touch or be stacked
  • Increase the firing temperature slowly to about 600 degrees to avoid flaking
  • from 600 degrees heat up to about 800 to 1,000 degrees
  • Let earthenware cool
  • Apply the glaze
  • Burn glaze in the oven, select firing temperature according to instructions
  • when glaze firing, the pottery must not touch
  • the furnace heat can rise faster in this cycle
  • keep maximum heat until the glaze is completely liquid
  • only then cool

Tips & Tricks

Before shaping the clay, you should beat the material vigorously and knead to remove all air. Caulk thicker ceramic pieces before firing so they do not break.
