I have just finished an epic ‘negotiation’ with a lovely liquorice coloured, 10mm thick piece of period plate glass. I started it yesterday evening, and finished it this morning. The complete process falls within a 24 hour period, but that would be what is termed ‘special pleading’. I just want to do one point per session per day. The glass is really lovely and the thickness presented some real learning opportunities.
This was the toolkit I started with. I wasn’t at home and forgot to bring my abrading stone (mistake). This morning at home I employed the abrading stone and a piece of leather to protect my hand as by then it was getting sore.
Because the glass was exceptional I wanted to make the most of it. This meant splitting it, and to do so I used a glass cutter and then gently hard hammered along the ‘cut’. This strategic use of modern and traditional approaches resulted in two decent sized pieces. Trust in God, and tie your camel, so to speak.
I have been told that the experimental archaeologist Bruce Bradley draws onto the core an outline of the flake he is about to remove, and then goes on to remove it. I outlined the shape of the point I was aiming for, thereby identifying the material needing to be removed.
I started using the pressure flaker to remove this excess material. However, the bump visible on the bottom left was proving problematic and so I tried the hard hammer. This resulted in what is called end-shock or hitting it at one point (the bump) and it breaking at another (in the middle). On the plus side I now had two more halves to work with. I continued with the left-hand piece.
This is an example of good edge preparation. The ultimate aim here is to apply deep invasive flakes to the upper face. In preparation to do so I worked along the edge of the upper face removing short flakes and creating a steep edge angle. This provides a good platform angle to then apply the desired deep invasive flakes to the upper surface. This platform preparation process can be used to simultaneously shape the piece.
However, it is not as simple as it sounds. Here I ran into problems again where the angle didn’t work and I created a lump. Whilst not exactly at this point, it was with a couple of these problems that I left the piece last night. This morning I was able to re-address these issues more patiently. To do so I had to work back to the last point where I could get a good preparatory removal, and then edge along from there. When I could go no further I would move back a little along the edge and take a large deep invasive removal out. This effectively removes a lot of supporting material and provides a negative bulb that can again be worked. Complicated to explain, and I am learning on the job so to speak. Dealing with lumps like this involves losing width.
Anyway, the net result is good. This piece embodies a lot of my learning and working out. The really beautiful museum examples are perhaps so because the working out had been done a long time before, a working out that translates into bodily understanding. Consequently, on the museum examples we see confident and systematic flaking which leads to a clean and aesthetic conclusion.
The one point per day may be a little optimistic for me. With hindsight, if I was really being goal focused I could have chosen an easier piece of glass and started the process earlier in the day. However, this glass is beautiful and I have taken time to negotiate a lot of issues that in the past would have been the end of the road. Furthermore, the first thing I did this morning was to get outside and continue with this piece. The deadline presents a focus upon an end product, and the learning process becomes a by product of the action. However a conscious focus upon the process is where the learning and understanding occurs. I have been reading about learning theory and this ‘making’ process is what David Kolb (1984: 30) has classed as Concrete Experience. As I sit now writing this blog I am reflecting upon this Concrete Experience and engaging in Kolb’s opposing category of Reflective Observation. Reflective Observation allows me to upgrade my understanding based upon the new experiential ‘data’ acquired through paying attention within the process. Doing so allows me to develop a new Abstract Conceptualisation or road map of what I need to do in order to make a Kimberley Point. With the next Kimberley Point I make I will be able to test out the usefulness of this new and upgraded Abstract Conceptual road map to see if it helps. The testing out process Kolb terms Active Experimentation. This brief four stage description isolates what is in fact a dynamic and blurred process of human action. However, the idea and practice of producing one new point per day provides a nice 24 hour learning unit within which this four stage process can occur, again and again. A further benefit is that it seems to get me out of bed in the morning!
