Neriage porcelain dragon eggs, a step by step process.

A few weeks ago I attended a weekend ceramic workshop with two ceramic artists from Finland, Nanna Bayer and Riitta Talonpoika. I had never heard of these artists before the workshop but once I had googled their work I knew that I would come away from the workshop with a lot to think about.

I have played about with Neriage or coloured clay before but I have never really thought about it seriously. I tend to work intuitively and let the clay or the idea lead me. Lately I have been spending an awful lot of time thinking about the dragon eggs and the different styles of eggs that I want to make. As I want some brightly coloured eggs as well as some fossilised rock like ones, I knew that neriage would be a technique that I would use.

Here is a step by step process showing how I made a swirly patterned porcelain egg.

Weigh out approximately 500 grams (1 lb) of clay and press a hole into the centre of the clay. Add 2 level teaspoons of coloured body stain. These weights and measures are only a rough guide as I wont know what worked and what didn’t until the piece is fired.

Then add a dribble of water to the powder to make a paste.

You will notice that I am wearing gloves, this is because a lot of the materials used in ceramics are toxic and can be absorbed through the skin. I have consumed enough toxins in the last twenty or so years to last me a lifetime and I don’t need any more.

You now need to wedge (knead) the clay until all the colour is mixed through thoroughly. I spent all morning making coloured blocks of clay yesterday. I used varying amounts of coloured stain for each different coloured block depending on its strength. I would highly recommend taking detailed notes so that you can alter the weights of the body stain if the coloured clay fires either too bright or not bright enough.

Also clean hands and cleaning your work space each time you finish making a coloured block of clay is really important. I have accidentally put a green thumbprint on the blue and red blocks, luckily it was easy to remove but this kind of carelessness can potentially ruin a mornings work.

I wanted a dark blue, sky blue and white egg to start with so I made a layered block of clay by putting slices together side by side. The pretty mauve colour will fire to an almost navy blue.

I banged the clay around a bit on the table to squish everything together. Then I sliced the block in half and started the process of carefully wedging the clay together.

I wanted a swirly pattern so I kept on wedging the clay until I was happy with the colour balance.

Once I was happy with the colour balance I put half the coloured block of clay aside for later and I cut the remaining block in half again.

I then put slices of plain porcelain with slices of the coloured porcelain together.

And started the process of mixing them together all over again.Once I was happy with the colour ratio of navy blue to sky blue to white I made two pinch pots.

Notice the scoring on the top of the pots, that is to help the pots join together. I slapped some slip onto the scored edges of the pinch pots and stuck them together and shaped them into an egg shape. I made a small hole with a needle on the base of the egg so that the air can escape when the egg is being fired. Otherwise the egg will explode.

Tadaa, the first experimental Neriage porcelain dragon egg. I say experimental because I don’t know if the porcelain will hold its shape when I fire it or not. These eggs are about the size of a goose egg at the moment and they will shrink down to smaller than that once they are glazed and fired. If the porcelain eggs dont work properly I will just use white stoneware clay.

I have made some similar sized eggs using CRT, a lovely robust stoneware clay that I use to make my platters. These eggs have a twofold purpose, first and foremost I will use them as test pieces to see how the porcelain fires, see what glazes work, that sort of thing. But their secondary purpose and the one that will give me the most pleasure, is that I want to be able to give these away to anyone who wants one as a memento of the open day next February 2011.

I also need to make a hammock to keep the eggs in so that they don’t get a flat spot as they are drying out. These are in a nest of old towels inside one of my slump moulds in the middle of the lounge room floor, which is okay as a temporary measure but it makes things a bit squishy inside the house. I want to have about fifty of these smaller eggs ready on the day so I best jump off the computer and get making.
