An artist in action

I thought I’d show you what I got up to on the ArtVanGo, Artists in Action stand at the Knitting & Stitching show last Saturday.

The brief was to ‘do what you would be doing in your studio‘, and so as recently I have been continuing my exploration of how I can use pigments gathered from the landscape in my work, that’s what I did.

I started by grinding up red clay from the beach at Cley (I ground two batches of this: fine and coarse) and seacoal from Wells beach (fine) and then made watercolour paint with it by adding gum arabic and honey …. I made quite a lot.

With paint in hand I started painting on Khadi paper supplied by ArtVanGo, first small pieces and then longer ones.

Each day, as I look out of the studio window, I see the creek slowly fill and then empty as   the tide comes in and goes out each day. The muddy marsh banks and creek bed are marked by the outgoing tide with hundreds of small ‘marsh rivers’ as the water drains off the banks into the channel. The soft mud is moulded and cut through as its surface changes twice daily. I am reminded of this quote by Ian Scott and Richard Worsley from their book, The Return of the Tide

‘This is a landscape in flux. Dunes creep. New channels cut the sandflats and slow, glassy tides spread thin smears of mud to build slick upon slick into new marsh.’

I am trying to evoke the marsh surface and the movement of water in these drawings.

I use a lot of water and a lot of paint and let it mingle and move. The coarsely ground pigment separates out as it is swilled around in the water.

Unfortunately I can’t make my own blue paint from local earths and rocks, so I have used a ready made indigo paint to add a contrast to the earth colours. A wax resist adds light and another texture.

My aim is to try and get the same diffuse, drippy effect on cloth as I have here on paper.

It’s amazing how much you can get done when you stand at a table for most of the day working!

Colour from the Landscape – Making paint

I’m busy at the moment jumping from one thing to another and I have several ‘makings’, new ideas and experiments going on at the same time. One of the most exciting is that I have been making watercolour paint.

Grinding West Runton chalk with a muller

I enjoy the fluidity of watercolour and last summer I made several drawings using pigments I had collected from the landscape mixed with water. Of course when it dried most of the grainy pigment just brushed off, and ever since I have wanted to have a go at making ‘proper’ paint in order to make drawings of the landscape from the materials of the landscape.

Grinding Hunstanton chalk – this chalk is whiter than the yellowed West Runton chalk

I finally collected together the right equipment (including the very handsome muller at the top of the page), ground up my pigments and had a paint making session. I have gathered five different materials from beaches along the North Norfolk coast. They are: chalk from Hunstanton, chalk from West Runton, yellow ochre from West Runton, Red clay from Cley, and sea-coal from Wells.

Hunstanton chalk and gum arabic/honey binding solution waiting to be ground with the muller

I have used gum arabic and honey as the binders for the pigment. Gum arabic is sap from the acacia tree and you buy it in large, hard, brittle crystals that have to be ground down to a powder and then dissolved in water. Honey is also added to the gum Arabic to make the solution fluid and easy to work. Honey is a humectant: it helps to pull in water so that the dried pan of colour gets wet and is able to release colour more easily onto the brush.

From left to right the colours are:

Hunstanton chalk white, West Runton chalk white, West Runton yellow ochre, Cley red,

Wells sea-coal black

I’m remarkably pleased with these paints. I have managed to grind the earths down to a surprisingly fine texture and I’ll show you the resulting paintings next time!

If you would like to have a go at making watercolour paint I’m doing a workshop at the Contemporary Textile Fair at the Landmark Arts centre, Teddington, TW11 9NN where we will be grinding and mixing pigments to make different types of paint. Hopefully there will be time to paint with it as well.

 

More playing

P1010688

When I make things I often do so obsessively, repeating things over and again until I have what I want. I’m sure this is a throwback from doing hours of flute practice in order to be able to play notes and to get techniques perfect. I’ve been making more samples that have been coloured solely with materials that I have collected from the ground: sea-coal, clay and chalk. I’ve tried grinding the ‘pigments’ to different sizes, experimented with heavy, light, loosely woven and tight textured cloth and fiddled around with different percentages of linseed oil and beeswax to make the binder. I now have enough samples that I’m happy with to enable me to start on the fun bit ….. the construction and putting together to see what is possible.

P1010682

I started simply by folding one sample over another or placing eyelets on top of one another or wrapping a piece round an edge. Just to see what would happen. I tried many combinations.

P1010692

I love the blend of coarsely ground chalk and the creamy waxiness of the binder …….

P1010696

and here there was an especially thick layer of wax that cracked on a fold. It’s very fragile, but is food for thought.

P1010691

This was the last sample I made, and to use everything up I threw all the last bits of grindings into the wax pot. The result is surprisingly good.

P1010678

These eyelets have been rusted with sea water before having a coating of the wax mixture and a trace of sea-coal.

I’m finally happy with the arrangement of each piece so now I need to sew them together. But I’m wondering! These samples are small  ….. I wonder how they would look big?

Chalk

Chalk is the bedrock of the physical landscape of East Anglia and it forms a ‘chalk belt’ that runs from the Chilterns to the North Norfolk coast. It has shaped the economic and cultural development of this region and forms some of its most beautiful and spectacular landscapes.

Hunstanton chalk samples

Although chalk is not as apparent in Norfolk as in other areas of Britain such as the South Downs, at Seven Sisters and the White Cliffs of Dover, it embraces the North Norfolk coast with chalk cliffs to the West at Hunstanton and to the East at West Runton. There are chalk pits and quarries all over the county, including just up the road from here in Wells, and sub-terranean Norwich is riddled with tunnels where chalk was formerly mined.

West Runton chalk samples

I am using chalk in my next piece of work and decided to collect the material from two different sites that mark the outer boundaries of my ‘place’: Hunstanton, where there are red and white cliffs, and the beach at West Runton where a vein of chalk emerges on the beach and at the bottom of the cliffs. The chalk I find at both sites has broken off from the cliffs, probably from wave action and the force of the tides, and lies scattered across the beach. Huge great lumps, too big to pick up and take home, lie at the top of both beaches under the cliffs, but smaller pieces have been distributed across the sand by the sea. I collect lumps about the size of my fist and smaller pebbles from both places. My intention is to grind them down to a powder and combine the resulting white pigment with a binder to stiffen and colour cloth.

Immediately I can see that the chalk collected from each site is different. The pieces of Hunstanton chalk are rounded and they don’t mark my skin or clothes as I pick them up. They are hard, dry and cold.

The West Runton chalk, on the other hand, is soft and buttery and the greasy surface of each piece has attracted a light covering of sand. It is damp and soft and marks everything it touches. By the time I get home my hands, clothes, bags and the car are covered with a film of white dust.

Before I even try to break it up I know that the properties of each sample is very different; the West Runton chalk will definitely be easier to process than the fragments from Hunstanton. I don goggles and a dust mask and whack a small piece of Hunstanton chalk with a hammer. Nothing happens. I try again, and again it doesn’t break. I get a bigger, heavier hammer. This time it cracks in two, but I can sense that using this material will be a battle. I try the West Runton chalk. One firm tap with a hammer and it breaks into four or five small pieces. It is so soft and breaks very easily. I continue tapping and soon I have a coarse powder.

I take a hard Hunstanton lump and start to grind the softer particles with it. It works well as a pestle and the powder gradually becomes finer. I take more of the softer lumps and continue crushing and grinding until I have quite a large heap. Fine powder rises up with the grinding action and I can feel it drying the skin on my hands and face – I’m glad of the dust mask.

The ground West Runton chalk is the colour of double cream. I suppose it has been yellowed by sand and I wonder whether covering it with water would purify it. I place it in a large bowl of water and wait. Bubbles rise to the surface as air is expelled from between each grain and after a few minutes the chalk has fallen to the bottom and the water has cleared.

fullsizeoutput_82a

I put my hands into the chalky soup and can feel hard lumps. I can squish them between my fingers and they disintegrate. I keep squishing, but there are too many to get a fine powder this way.

fullsizeoutput_835

I pour off the clear water and realise that, of course, all the large sand and chalk particles  are still combined. I place the creamy, chalk mixture on a tray and leave to dry. Soon I’ll be able to mix it with a binder and make a form of coarse gesso to form the foundation of my next piece of work.
