SAGGAR FIRING

Thrown porcelain forms, burnished and layered with terragisilata and polished in between layers. Biscuit fired to a temperature of 1050 degrees centigrade. Fired in saggars i.e. an enclosed vessel, ceramic or old tin paint cans with a lid for example.

The pot is placed in the container with sawdust, salt, metal oxides. banana skins orange peel copper wire etc., and fired in a gas kiln to a temperature of 650 degrees centigrade When the kiln has cooled sufficiently the pot is removed washed and all the sawdust removed. It is then polished with a soft cloth with beeswax. The pots are purely decorative and will not hold liquids.


RAKU

Raku is a Japanese technique. Special raku glazes are used which melt at a low temperature. My pots are mainly thrown forms or handbuilt bottles, after biscuit firing the glaze is applied and they are fired in a raku kiln to approximately 750 degrees centigrade. Whilst the pots are red hot they are removed from the kiln with metal tongs and placed in a galvanized dustbin together with sawdust. The lid is placed on immediately creating a reduction atmosphere. They are left in the bin for about 20 minutes then taken out and plunged into a bucket of cold water.



NAKED RAKU

My naked raku pots are made as for saggar firing. After biscuit firing I mask out certain areas using masking tape, wax resist, paper etc. They are then dipped into a resist slip which resembles thin cream and left to dry when a glaze is poured over and the masking tape etc is removed leaving behind naked areas.

The pots are fired in a raku kiln to a temperature of 750 degrees centigrade. The pot is removed from the kiln whilst red hot with tongs and placed in a dustbin with sawdust. The lid is placed on immediately creating a reduction atmosphere. After approximately 20 minutes the pots are removed and placed in a bucket of cold water. The outer layer of slip and glaze are removed leaving behind the wonder of naked raku. They are called naked raku because there is no glaze covering the surface. Finally they are polished with a soft cloth and beeswax.

Raku firing - pots are taken directly from the kiln and placed and covered in sawdust.

After about 2minutes the pots are takenout and immersed into a bucket of water.

Once cooled the pot emerges form the water, it is then polished.

The pots are removed from a red hot kiln.

For naked raku the pots are placed in a dustbin with sawdust and other combustable materials such as newspaper.

Once the pots are in the dustbin they are covered with sawdust and the lid replaced creating a reduction atmosphere.
