Squares with Two Circles

Arising from our first theory/practice session last Tuesday I’ve identified the artist Barbara Hepworth as a key reference to my project, in particular a bronze work of hers called ‘Squares with two circles’ which I saw a couple of years ago at the Kroller Muller sculpture park in Holland.

I remember I was drawn to this sculpture enough that I sketched it – the simple geometric forms at a slightly jaunty angle and its pleasing sense of balance gave it a kind of purity of form. The fact the lines aren’t parallel gives it an organic quality that helps it fit in with the natural environment. On each side only one of the circles funnels out which gives the two circles different qualities of depth and the way the patina on the surface is lighter in the upper half makes it appear to be dissolving into the sky at one end and firmly grounded on the other. The original form was made in 1963 although copies were made later which explains why there is also one in the Yorkshire sculpture park.

I’m interested in Hepworth’s forms in regard to my current project because of the way they act as framing devices for their environment, the holes referencing windows. Her emphasis is on form and texture rather than colour. I’m interested in the ways the forms I make create different tones of dark and light by the shadows they cast, so how colour is created by the artist in collaboration with the environment.

In the sculpture park the work is displayed outside the Rietveld Pavilion, a building in which you are at once outside and inside. This is an interesting space because of the way it blurs boundaries, the architecture more a huge sculpture you can walk through really. Many more of Hepworth’s artworks are displayed here which is appropriate since her work explores inside forms with carefully constructed positive and negative space.

I found information about this work on the Tate website and it discusses the holes in the form: ‘The integration with the landscape – one of Hepworth’s abiding concerns – is made actual by these openings, through what she termed the viewer’s ‘sense of participating in the form’ (Bowness 1971, p.12).’
I want to explore this idea that the audience can ‘take part’ in the form. It’s almost as if the interaction between you and the artwork becomes a performance, because you are not just seeing the artwork but using it as a device to look through, to perceive the world differently through, like a telescope or pair of glasses.
Placement therefore becomes important because what the sculpture ‘reveals’ through the frame will depend on where you stand in relation to it. It was important to Hepworth that the sculptures were displayed in the landscape as she explains: ‘I always imagine the sort of setting I would like to see them in, because I firmly believe that sculpture and forms generally grow in magnitude out in the open with space and distance and hills’ (Warren Forma, 5 British Sculptors (Work and Talk), New York, 1964, p.15)
I believe she may be speaking about the powerful way the changing of natural light and weathering of the material (through the day and seasons) can bring a sculpture to life in a way placing it in a room in an art gallery can’t.

Blue flames and broken fingers

Inspired by the pit firing on the Pottery throw down, Nina, Nam and I tried our own smoke firing over Easter with the help of the fabulous Ian Hinchliffe, potter at Quarry Pottery in Corris Craft Centre. We took a similar approach to the oil lamp bin firing Mick Morgan helped us with before the holidays – lining a bin with newspaper then dried wood chopped down as kindling.

The pots were wrapped in copper and steel wire then generously sprinkled with copper carbonate, cobalt oxide, black nickel oxide and a mixture of blue, yellow and pink commercial stains. Dried ferns, pine needles, leaves and banana skin were also added before they were wrapped up in tin foil. Once surrounded by the kindling we set the bin alight though the holes in the bottom and kept adding wood for a good few hours, the metal gradually turning red hot.

More stains, salt and oxides were sprinkled on during the evening, which, if they didn’t make much impact on the surface colours, definitely made for some spectacular electric blue coloured flames for us to watch. The experience of sitting around a fire with a group of people as darkness gently fell over the welsh hills, our shared hopes invested in our kiln babies and mesmerised by the flickering light and warmth of the flames, was an unforgettable experience. The raw power of the flames made me feel connected to something primal. I suppose our early ancestors would have felt the same awe sat around their bonfires at night. Although perhaps it’s just that every potter is a bit of a pyromaniac.

Opening the kiln in the morning, we were surprised to find all the foil burnt away but the pots hadn’t turned as dark as we expected. The colours came out best on the slipcast porcelain vessels with striking flushes of pink and constellations of smokey greys and browns on their smooth surfaces. Burnishing the pots beforehand would have improved the surface quality and leaving them in a reduction atmosphere for longer may have turned the surface darker.

Enamelling

In a similar way to how glaze powder is fused into glass on ceramic, enamel powders are fused onto copper. The temperature however is a lot lower, any higher than 800C and the enamel starts to discolour, as I soon found out.
Before and after shaping the copper needs annealing and then plunging in cold water to cool. Gum arabic is painted onto the back of the shape after cleaning, then backing enamel is dusted on top and the copper placed in a small kiln. When opened the kiln temperature plunges and you have to keep an eye on it as it gradually climbs back up to 799C. On the opposite surface different coloured enamels are fused on in separate firings, although the process is a bit more difficult than I expected. The colours don’t behave as planned, burning out before the kiln reaches optimum temperature or leaving speckled textures (which can look nice – a bit like a dusting of snow).
I’d like to know if these copper enamels can be used on top of bisqued or glazed clay. Alternatively, perhaps panels of enamelled copper (maybe a maker’s mark) could be inlaid into the clay after firing by being stuck on, although I’d have to contest with shrinkage.
