Whilst away on holiday I paid a visit to the Whitby Museum, well worth it if you should get the chance.
Inside there is lots of treasure, and this is a photograph of a lovely Neolithic leaf shaped arrowhead found locally.
This, by contrast, is my point from today (and yesterday) made from a really thick piece of glass given to me by a friend, Stephen Poole.
It started out as an exercise in exploring the differing functions of hard and soft hammer in the process of reduction. In this respect it was successful as I now have some nice flakes for reference purposes.
However, the striking difference between the flakes produced by the different methods was also useful for me in deepening my understanding. Thinning a nodule to produce a handaxe is a process that I have observed (and filmed) a number of times. Karl Lee always emphasises the import of understanding angles. The stark contrast between these flakes is allowing something to fall into place for me (conceptually, not yet practically!) The hard hammer is perhaps more about producing angles to work with. The soft hammer more about exploiting those angles to thin the piece effectively.
I don’t like this arrowhead. It is too thick and lumpy and will probably go into the box in my back yard where my not quite resolved experiments end up. However, I have made it my point for today (made yesterday, finished today) which keeps the process, and therefore learning opportunities, going. What is intriguing for me is how the actual flakes themselves are helping me understand the process differently. Learning from the materials seems to encourage me to think about something I already know about in a different way. This thinking through objects is obviously something we do a lot within archaeology. It will be interesting to pick apart how the objects have added to my understanding in a way that observation and explanation have not. Perhaps the theme for another post.
I have some workshops planned aimed at primary school children studying the prehistory of Britain. Following the theme of this blog, one of the activities is to bring together the components necessary for the kids to make a Bronze Age arrow. Rightly or wrongly, I am a little cautious about letting small children loose with flint or glass arrowheads so I thought I would get some 3D prints. The flint originals were a Neolithic leaf shaped example and a Bronze Age barb and tang arrowhead both produced by John Lord for Elizabeth Healey’s teaching collection . These originals were scanned in by a colleague Tom O’Mahoney.
Tom also scanned one of my glass barb and tang arrowheads to see how the scanner would cope with a reflective and transparent material. This example had to be covered in talcum powder before scanning.
After scanning, two prints of each of the flint versions was produced for me by Ed Keefe from the print unit at Manchester Metropolitan University (ManMet).
The first two examples on the left have some horizontal lines running across. Ed described this as similar to when a photocopier is running low on toner. Consequently he printed them again in the more transparent material. The second two are excellent ‘plastic’ reproductions of ‘original’ flint reproductions. However, the most impressive aspect is the price. Because prints are priced by the cubic centimetre each arrowhead worked out at £2.50. Full colour versions would have cost £3.50. My scans can be uploaded to sites such as Sketchfab or Thingiverse and therefore downloaded free of charge by teachers with the print costs being minimal.
The workshops are still at the planning stage, but I have been impressed by the results and the prices for this process. I would certainly recommend the 3D print facility at ManMet to anyone who thinks the process may be useful to them. Ultimately though, it depends what the kids think!
I had the opportunity to have a wander around Chorlton Ees one morning last week and came home with quite a few pieces of old glass recovered from the roots of fallen trees.
This lovely blue piece in particular caught my eye and I like to think it is the base of an old Milk of Magnesia bottle.
As you can see it is chunky and I wasn’t quite sure how well I could reduce it. This is because it is both narrow and thick and I was worried that I may run out of width before it was adequately thinned. Anyway, today has been a beautiful day here in Manchester and I got to spend a couple of hours outside playing with it.
I am pleased with the result. It has become a Neolithic leaf shaped arrowhead, similar in proportion to some of the stone examples I have seen. The edges are sharp, the tip is good and it is fairly symmetrical. What really makes it stand out though is the lovely blue colour. When Nick Overton sees this photograph he will immediately focus upon the very, very small section of original surface left in the middle. All I can say Nick, is: “when a pickpocket meets a saint, all he sees is pockets!”.
