26.10.07- writing about perception [and making moulds]

Monday was spent reading about perception and starting to put down some words towards that section of the thesis.
I remember coming across the writings of Richard L Gregory FRS, the Emeritus Professor in the Department of Neuropsychology at Bristol University last year and was interested in his work on illusion, which he uses to further his investigations into how sensations are interpreted as perceptions. In looking for online definitions of perception I came across his website. It’s a valuable resource that allows readers to download all his research papers. What is particularly useful about Richard Gregory is that he is at the forefront of current research.
Philosophers since the Ancient Greeks have studied perception. Since that time the dominant theory has been ‘passive perception’ – whereby perception came predominantly from the interpretation of sensations, in a linear way. However, the theory of ‘active perception’, is gaining momentum. Richard Gregory states that perceptions are 90% or more stored knowledge governed by rules generated through experience as we grow up.
In other words, when I look at a container, my brain doesn’t have to rely on very much visual information, as it knows what to expect from the countless times it has previously encountered a container. It will contain something or have the ability to. As a potter who has made many thousands of ceramic containers my brain is taken up with the aesthetics and function of the object, rather than identifying it. But I suppose that is what most of us do to a greater or lesser extent.

On Friday some tests came through that are part of my attempt to disrupt this process. I have thrown a series of cylinders; one without a base, one with a cone instead of a flat base etc. each was decorated with one matt black surface and one black metallic shiny glazed surface. I am interested to see if the glazed surface appears to float or loose definition due to the reflections.

The other big project this week was the making of the mould of the torus 03 CNC milled model. When I arrived on Tuesday Stephan was already at work, so I helped him by mixing plaster. Later on he left me to make the top half, which seemed to go smoothly. The following day we separated the two halves but it wasn’t until the evening that I finally removed the model. The mould is a success, but now we have to work out how to slip cast from it. Before catching the train home on Friday I went to speak to Robin Levien who is involved with Ideal Standard, makers of sanitary ware. He was very welcoming, showing me around the workshop below the studio where the team makes highly skilled models from blue Styrofoam. Robin will contact the manager of the Middlewich factory to arrange for me to visit and discuss the casting of the piece. Ideally I need to make the visit before my French trip.

14.09.07 -The Torus & the Möbius Strip

Some weeks ago I gave my friend Ivan Payne one of my thrown torus forms to experiment with. He’s an interesting person to discuss my project with as he completed his MA at the RCA last year. One of the brightest lateral thinkers that I’ve ever come across, something new always arises when we toss the ball back and forth. The end result of his unusually quiet investigation was a cut that spiralled up the inside of the torus and back down the outside connecting seamlessly to its starting point. In theory the torus had been bisected, but was very much still one complete form. Both the Torus and the Möbius strip are one-sided surfaces; if a Möbius strip is bisected lengthways it just doubles it’s circumference, which makes me think that the same thing was happening here. [What would have happened to the torus if it was made of flexible rubber?]
I went on to widen the cut & remove a 1cm wide strip of clay from the torus, producing an unsupported gap between the two ‘halves’. At that stage I found it impossible to work out whether the strip of clay was a Möbius strip.
From the workshop it was back to Rhino 3D on the computer in the hope that I could analyse and develop this phenomenon. At this stage I had the feeling that the link between the exploration of the torus was taking me back to the Möbius strip that played an important part in the genesis of this project. After some additional instruction from the very helpful technicians at Simply Rhino I described the spiral line onto the surface of the torus. In the ceramic test piece I was trying to visualise what the strip of clay would look like if it could be removed in one piece from the torus. In Rhino it is possible to take and develop the line into a ‘solid’ ribbon form. A single spiral strip doesn’t have a strong visual link to the torus it evolved from, so I went on to produce a double spiral,then a quadruple spiral, the latter appearing like a skeleton of the torus.
In exploring and developing the torus form, the use of 3D modelling software has been invaluable. It has enabled me to visualize the evolution of the form, literally adding another dimension to the creative process. My attempts to throw the toruses has demonstrated that a great deal of skill is required to realise the different stages of development, There is absolutely nothing wrong in that, it is the age old process helping to produce high quality craft and art work. However, I have chosen to produce forms that conform to a particular set of proportions and so far my throwing skills don’t allow for a very precise reproduction. It’s partly due to the torus being an enclosed form, preventing me from gauging the thickness of the clay wall.
