Building Brick Sculptures on a Monumental Scale.

Whole buildings are built from clay-mud all over the world. They last for centuries and can be huge. They are all built  basically like coil-pots.

I build the structure of the big sculptures in much the same way, add on  the artwork and  then cut them up (hollowing where necessary) for firing. These days I use this method for most of my sculpture but with smaller pieces (under 2 metres)I work quite intuitively. The big ones you need to plan like a military campaign because supports will need to be built in from the outset in order to be rigid enough to work and to cut the piece up. Budgets must be stuck to and Volunteer’s time is very precious.

This is a very different method from building with un-fired Bricks, which is mostly a subtractive, carved process. Using the raw clay allows for a lot of adding and modelling. They are both great techniques and Gwen Heeney’s excellent book ”Brickworks” is well worth reading. It is full of good advice.

After talks/workshops with the local community, research, writing a plan-of-work, time-table  and making a  Scale Model, draw the out-line of the sculptures foot-print onto the floor.

Using very soft  Brick-clay  lay down first layer at around 5 cm thick. Allow to stiffen. Soften top edge w/ water, rub to a slip, add next layer (approx 10kg clay ‘coil’ 40cm long), ensure good join, draw the clay upwards. You can get about 30 cm in height. You can lay a strip of plastic along the top to keep that edge soft for the next join. Joints must be perfect so that the final sections are strong enough to handle.

Note the finger marks; leave these: use them as strengthening for the walls in the manner of corrugation.

Inner ‘Support Walls’ are built thinner, inside the form. Clay supports shrink with the Sculpture. They will be discarded and re-cycled when the Sculpture is cut up.

Like all coil-pots, lower sections are wrapped in plastic to prevent over-drying; you will need to be able to cut through all layers so they must not get too hard and over-drying/shrinking will cause nightmare cracks. The thickness of the walls can be reduced as you go up to reduce weight.

Chunks of memory-foam can be put inside to support horizontal walls; the foam will shrink w/ the clay.

This will be removed once the huge weight (2 tons) of the upper parts of the sculpture are cut away during the dismantling .

Wooden supports can’t shrink w/ the form so may cause bad cracks but they have their place.

We made 7 adjustable metal/plank brackets to support a wall that leaned outwards by nearly 40 degrees. They had to stay in place until upper sections were removed. There are whole sofa cushions inside supporting the roof!

Balarat is 6 metres long x 2 m high and took 7 tons of clay. We built it at the same time as Ocean Colliery Pit Marker (5m long, 5 tons of clay), seen in the background. There is a lot of drying (timing is everything) so having 2 on the go really maximises the use of your budget; we were able to build and install these both for £40,000. Countless wonderful people were involved and it all took over a year.

The Sirhowy Wyvern has a tunnel running through it (with art-work inside of children working in coal mines, some done by kids like these awesome girls from the Youth Club). We had one clay support-wall half way along to support the roof and this allowed us to get inside from either end to work.

To add on art-work: spend a lot of time softening the surface, add clay, ensure a good join, add clay to block-out art work, wrap in plastic to allow the water to travel from the soft clay into your hardened wall. Un-wrap when the clay has all reached a similar hardness + complete the art-work.

As walls are complete they can be smoothed, carved and art-work added and refined. All the tools are normal sized pottery tools and bits of wood. Plastic wrapping and containers of water placed inside can slow the drying, fans (pointed towards walls, not at the clay) and dehumidifiers can speed it up.

Calon Lan was the first really large build I did with a group and only the 3rd one I had done. Many people worked on this piece, using all sorts of techniques and styles. We had lively discussions about the building methods and art-work and worked it out between us. Especially with these early pieces it was terrifying! With each sculpture I have changed the technique a bit. You will do the same, adapting it to your style and clay.

This wall on Balarat was built extra thick in preparation for the remarkable volunteer, Wendy Sage, to carve on this fantastic view of the village taken from archive photographs. Wendy worked on this panel for 6 weeks and did a lot of the other art work on the Blaengarw Sculptures.

As soon as the top area is firm enough to handle you need to start dismantling the Sculpture. Cracks will be showing up as the whole thing tries to shrink.

Take photos all around the Sculpture. Enlarge + photocopy.

Start cutting from the top with a normal ‘cheese-wire’. Aim for around 30 cm square; sections that are too large will be hideously heavy, crack and worst, warp in the firing. Try and keep the edges of the sections at 90 degrees to the front surface for yourInstaller’s sake. Lay the sections onto memory foam so they don’t distort/get damaged. Draw on your photocopy  Photo-Map the cut’s shape and record the number. Mark the number on each side of the edges of the section (incase one number gets smudged). These Maps, numbers, a tracing, on plastic, of the outline left on the floor of the foot-print of the sculpture and the Scale model are now your most treasured possessions until the sculpture is installed and loosing them will haunt the many nightmares you will have about the whole process.

Once sections are stiff enough to handle without distorting trim away the excess thickness leaving a good 5 cm minimum. ‘Gouge’ out, using loop-tools (or an electric drill on leather-hard sections) a random pattern of channels in the back of the sections that will reduce the thickness to 2cm at any point, act as a grid of braces to deter warping and give excellent grip to the cement that will hold them all together. It’s got to be said: this is not the fun bit….

Dry slowly using a dehumidifier/memory foam support/regular turning for at least 5 weeks. Fire SLOWLY!!! Bear in mind that many brick-clays contain stones; these must be fired extremely slowly passed 500 degrees C to allow vaporised minerals to escape or your sections will ‘bloat’. Luckily I’ve never had this happen thanks to the kind guidance from the  guys at Coleford Brick and Tile who don’t find bloating a laughing matter even though a bloated brick looks like a rugby ball! Be wary, too, of the low melting point of some brick-clays.

I fired all the sections packed in the kiln on their edges (flat seems to invite cracks/distortion) in my Cromartie 16 cu ft Workhorse Electric Kiln in batches of up to 40 sections. 1 ton of sculpture seems to yield about 50 sections.

Installation needs an imaginative Builder with the patients of a saint who will, non-the-less, come to hate your guts. Lay a strong foundation w/ reinforced concrete, build an internal structure of breeze-blocks/infill/steel bars,’clad’ with the sections of sculpture and point up joints. Installation will generally use half your budget.

        Installing a ceramic sculpture with sections.

Sculptures made in brick, using any of the various techniques, is incredibly laborious. But they are more durable than any other material. They are the archaeology of the future. More people can be involved in making them and they can be much more affordable than other  materials. The process of the installation will be more like dry-stone walling than brick laying.

Using the Scale Model:

The scale model was used to build the form in wet clay. Changes will have been made to enhance the form in it’s full scale.

There is an 18% shrinkage from wet to fired with Coleford Brick clay so the scale model will be 18% too small.

Spacing and pointing will also affect the installed size.

So the scale model is only a useful guide during installation.

The Sections:

The sculpture is built as one in soft clay and then cut up.

Once the form is built it under-goes a controlled drying period to the point where it can be cut. Obviously the lower layers are very hard by that time, and the upper layers less so.

Cutting has to be done in such a way that the fragile form does not collapse. That is why the numbers follow the sequence they do and why the cuts are where they are.

Cutting up is very difficult and hard work. At each cut the Map is marked, numbered and the section numbered. Mistakes are easily made. 

The sections are heavy and can be awkward to lift. They are set down on memory foam and then trimmed back as much as possible. A grid of gouges in the back helps to hold the shape during drying/firing. Happily they also provide excellent grip during installation. Every care is taken but inevitably some get damaged. Once the clay has passed a certain point in drying it is best to repair this damage after the firing.

 Each section section is carefully handled/supported/turned during a long, very slow drying period of 6 weeks.

The sections will have been divided over a number of firings. No firing is the same and where the section was in the kiln also creates unique conditions. Because the shrinkage is so high ( 18%) and the Coleford Brick clay is being fired to a temperature close to it’s melting point to gain the near vitrification and strength, this may make significant differences to the fired section’s size.

So sections may well have warped, shrunk un-evenly and cracked. They can be trimmed or cut with power tools. Badly warped ones can be cut into several pieces so that they can set well in the form.

Priorities:

The parts that will be focal points and define the sculpture.

                                                      Edges.  Carvings.  Holes.

The hole is focal- people will usually go up close to the holes if they can. But they can be ground with power tools.

Edges can also be ground into line to a certain extent but it is very difficult to re-produce the right texture.

All three are very important but the carvings are the part that needs to be set most carefully.

The Foundation:

The installed sculpture may be solid with infill and very heavy. The foundations need to be adequate. Steel re-bars should be set to re-enforce /anchor the sculpture.

The Layers:

The installation can only progress one layer at a time, starting at the base. If the base layer is angled wrongly that error will magnify with each subsequent layer making it very difficult to look after your 3 priorities ( above).

Careful planning of each layer will make a big difference.

Sections can be trimmed and spacing can be varied. Have a box of spare mosaic tiles/pebbles to decorate very wide gaps. Leave enough gap to point: This sculpture will stand for centuries and all precautions should be taken against water/ice.

         – Using the maps sort the sections into groups.

  • Using a washable paint write the numbers on the out-side of the section.
  • Using a marker-pen write the number of the adjacent section shown on the map, on the inner-edge. Also mark ‘top’, ‘base’ or a this way up arrow.
  • With smaller sculptures or parts like figures:

          Place paper or plastic on ground.

          Starting with the top layer, place the sections using stones/bricks/breeze blocks to support them. Make wedges/spacers and hold in place             w/ duct tape.

          where necessary fix sections together with quick drying cement ( this can be knocked off later.)

          Photograph/measure/make notes.

          Trace the ‘foot-print’ onto the paper. Cut it out and use to guide the next layer down.

         -With large/wide sculptures:

          Set the base layer. Support/space well as above. Hold the next layer sections to each join to check the consequent angles. Lay that next                 layer on the ground around the installed layer and check as much as is necessary that the fit is good.

  • Once you are sure they are correctly placed, fix them in with cement. When that is set put in your next layer of re-bars and infill.

Pointing:

Coleford brick clay is very dense and has extremely low porosity. Ensure your pointing material is suitable to the ceramic.

Red sand gives a good, long lasting match to terracotta colours.

Coloured mortar from Tarmac (http://www.tarmac.com/mortar/mortar/coloured-mortar/  ) are good.

Colour dyes do not last well in sun-light.

The whole process is spectacularly laborious!! And exquisitely low-tech. There is a job there for every Volunteer of every ability, from teen-age lads building the structure to Grans, kids and every-one in between doing art-work, people who like to stay clean doing research and collecting reference material, the local Cafe feeding you all the vast amounts of cooked dinners it will take to fuel the gruelling lifting and shifting required, people stepping in off the street to give you an invaluable ‘fresh eye’ on how it looks. The finished Sculptures will last for many generations, become landmarks and the pride of the area and finally the archaeology of the future.

The River Series is an off shoot of the Wind Water Fire series merged with the Harbingers. It coalesced here in the Beacons in 2012 after 12 years in the stunning Upper Rhondda surrounded by waterfalls.

When I first tried the Scarva black clays about 3 years ago I made a number of reclining figures and harbingers many of which were so awful they got recycled! But this one with a water theme I have hung onto knowing I wasn’t done with it. A lot of the work from it is now showing up in The Edge landscapes. Moss and lichens are the perfect finishing touch.

I’ve been off down various roads with it, some of them dreadful!! I’m definatly not done with it .

Like the Harbingers it is an environmental theme about the land and our relationship with it. Knowing you have drinking water running clear near your home is a treasure that means more to us all than we dare to think.

After the move to the Brecon Beacons I found we had this stunning river just below our new home. It is the river of the Henrhydd Falls, south Wales’s tallest Falls made famous by the last Batman movie.

The Half A Century Series.

The Half A Century Series began some years ago when I turned 50 in 2011. That is traditionally a prime time to do some major reviewing of one’s time in this nutty life! It is a largely autobiographical series but I hope the  images and curves feel familiar to many of you.

The forms are figurative but more to do with the internal experience of the body, movement and emotion.

Contemporary Dance Performance and Photographs like this wonderful picture are hugely influential in this series.

It started with these figures in a constructivist style I really like but only used occasionally at that time. I had had an unexpected surgery that took the strength and some movement from my arms for a while so working solid in this scale was not an option.

The Musing Series is not so directly personal but they were made at the same time as these black figures and they are linked.

The Life’s a Beach Series preceded Half a Century but it is also part of the same on-going theme. It is 10 reclining figures about a story I was told about Port Talbot; The area was a stunning beauty spot of huge, gorgeous sand-dunes. In the early part of the Industrial Revolution tourists came from all over the world to wonder at the grace of the  curves and forms created over millennia. Then it occurred to someone that all that sand was handily placed for making plenty of concrete to build an Industrial Port…..! The figure’s form is taken from sea-worn coast-line and the wry gesture of a Mae West style character smiling inwardly at the lack of appreciation for the nuanced beauty only age and experience can bestow.

August 2017.

The continuation of this series is Beyond Half a Century where the ideas move forward from the transitions at 50. This turn in the road came when my mother died after a very long and complicated struggle with illness. As in the earlier forms in the Series, the sculptures are very direct and un-edited outlets for how I feel at that moment. Once the expression is fixed I will work on for as long as it takes to clear off any irrelevant material until it rings true. They can be about all sorts of things. I turn to this work to clarify thinking that words wont un-ravel or when I am over-whelmed.

These pieces are from 2017.
