Raku Ceramics Process - Stage 3 - Firing

Now we get to the really exciting part of the Raku process where we start to see the results of the firing which uses both smoke & fire to achieve it's unique qualities.

The firing in a Raku kiln takes approximately 30 minutes at 1800°F.

Using tongs, the pieces are removed from the kiln when at it's highest temperature (which differs from other firing methods) & are placed in some form of metal reduction chamber such as a rubbish bin. This has to be done very quickly.

The items are covered immediately in a flammable material such as natural wood sawdust as seen in our process (newspaper, cardboard or leaves can also be used), to inhibit the absorption of oxygen to the molten enamel. The smoke from these materials contributes to changing the colours and patterns of the Raku pottery. The fire feeds on the oxygen within the metal container plus it also draws the oxygen out of the Raku pottery & it's glaze. 

You can see from the pictures below how this is all starting to come about.

Raku Ceramics Process - Stage 2 - Glazing

This week we have some pictures showing the glazing process which takes place after the bisque firing.

Glazing work for Raku can be done by various methods - dipping, pouring, brushing, spraying, splashing, dripping, sponging. We brush on our glaze using a combination of glazes to give vibrant contrasts of colour.  Some Raku glazes produce cracking and result in a spider webbing effect. You can also combine both a glazed and unglazed natural smoky effect on the pottery.

The application of a glaze has a direct effect on the end result & although we may intend a certain type of final effect there are no guarantees & it is always exciting to see the end product. This is also why the meaning of Raku is 'Happiness in the accident'.

Next week we'll look at the second firing & see how some of the items turn out.

Raku Ceramics Process - Stage 1 - Design Creation

Many of my customers ask how my Raku ceramics are made, so I have created this new blog to show the process. I will be updating the blog with pictures on a weekly basis.

These ones show the tools that we use, the cutting out of the clay, the designing, the drying process & the first firing. The overall process is quite lengthy but also very rewarding & therapeutic.

The bisque firing is the first of two firings. The goal of bisque firing is to convert greenware (unfired pottery which is very fragile) to a durable, semi-vitrified porous stage where it can be safely handled during the glazing and decorating process.
