Reflecting upon my Bronze Age arrowhead workshop


The title suggests that my workshop is about producing a Bronze Age arrowhead, but upon reflection I realise it is actually about people. The workshop went really well, so much so that I am keen to do another one soon. I received good feedback but most importantly I really enjoyed it, and I think the participants did as well. In total there were ten and a half of us. Rachele, from The Old Abbey dipped in and out, in between other pub related tasks. Of the nine participants I knew six already and three people were new to me. Interestingly, three of the participants were engineers. The day was sunny and everyone was in a good mood and the group mix was good.

I had them for four hours and I had integrated a half hour introduction explaining how stone tools have been used to structure our understanding of prehistory. This is a compressed summary of around 850,000 years of British prehistory in 30 minutes. Highlights include an Acheulean handaxe (made by me), a Bout-coupe handaxe (made by me), a blade core and blades (made by John Lord), a bladelet (made by me), Neolithic leaf shaped arrowhead and Bronze Age barb and tang arrowhead (both by me). The idea is that they can ‘handle’ their way through prehistory and it worked well. I have a day-school coming up in September and I am going to develop this section so that it is two hours and includes a Powerpoint and activity. I feel really pleased that I have produced an almost complete teaching collection in line with the historical discussion. After the main lecture bit we explored how can we develop an understanding of the stone tools themselves. One approach is through experimental archaeology, or Learning Through Making, and off we went. I introduced them to a Kimberley point (made by me) to provide a linkage between archaeological stone tool production and the ethnographic use of glass. This provided a segue into beer bottles.

Removing the base of the beer bottle using a length of wire is great, because people are amazed at how easy it is. After everyone had obtained their base I led them through hard hammer, soft hammer and pressure flaking. Without providing a blow by blow account, some people got it and others didn’t. In the middle of that bell curve sat seven people. I worked through the process in a linear sequential way starting with hard hammer and ending with pressure flaking. I may change this a little as really they need to move between the three tools on their journey through the process. The linear approach may not therefore be that useful.

It was a four hour session and based upon feedback I am going to instigate an official break in proceedings, meaning everyone would have a break at the same time. There are actually many advantages to this. First of all it gives people the chance to get to know each other a little. Secondly it provides a respite from the intense concentration that is required. Thirdly it will provide some business for the venue who kindly hosted my event free of charge. Along the same lines, a mini ‘icebreaker’ at the beginning has been suggested.

This feedback is really useful because it has highlighted to me the point mentioned at the beginning of this post. The workshop is actually about people, people who have come together in order to make a Bronze Age arrowhead. It is a social, as much as a technological process. Getting their feedback is a great reminder of this, and great way for me to think about how I can craft future workshops around the people taking part.

The best bit of feedback I received on the day was “that was really interesting. I am never going to do it again!

My thanks to Rachele for encouragement and hosting, and Brian Madden for these excellent photographs.


Bronze Age arrowhead workshop: the sequel

Rachel at The Old Abbey Taphouse has been kind enough to give me the space to run a second workshop with them. Drawing upon my Pop Up Business School experience, videos attract more attention than posts with just photos, or text only. Consequently, here is my promotional video.

My friend Brian Madden edited this video for me, and pointed out how about half way through (1.09 seconds) one of my neighbours shouts out “I can’t find the chocolate“. Soon after (1.23 seconds) I can be seen eating some chocolate. Who said subliminal advertising doesn’t work.

SMART Archaeology glass arrowhead workshop

On Sunday I was fortunate enough to run a workshop for the South Manchester Archaeology Research Team using bottle glass to produce an arrowhead. My aim from this session was to get photos and feedback on my teaching and how I am organising the process for the learner.

I now have a very structured approach and clear outcomes for the session: use hard hammer, soft hammer and pressure flaker; produce something like a Bronze Age barb and tang arrowhead; recognise that the equipment needed is all accessible and therefore personal practice can be developed (if desired).


smart 7All those boxes were ticked. I also added a feedback section that was designed to be useful to me, but also encourage some reflection by the participants on what they had learned. This is following Kolb’s learning cycle model and I think it is a valuable addition.

Feedback from a previous participant has encouraged me to use a whiteboard, in particular to explain platform angles. Having a clearly established process allows me to punctuate it with whiteboard explanations before the participants have to do it. This too is really useful.

Pressure flaking: it is not easy, and not easy to get people up and running with it in a three or so hour session. Consequently, the later stages involved a little interference by me to get rid of any difficult bits. I have a barb and tang flint arrowhead produced on a flake and made by me. One side of it has a nice row of deep invasive removals. They were produced by John Lord showing me how to pressure flake. The opposite side has an intermittent row of shallow flakes produced by me, not really getting it. I think if John Lord does a bit on his students arrowheads, then it is totally legit.


And everyone did go home with something approaching a barb and tang Bronze Age arrowhead. I would like to thank Ellen McInnes for suggesting this and Andrea Grimshaw for the organisation and making it happen. Based upon the feedback I can say that we all got something from the day and I think we all enjoyed each others company, so a result!

A pressure flaking photo essay

This post is brief through necessity as it was done on my phone, on the tram. It shows the prescribed Kimberley Point process applied to the side panel of a period glass bottle. The last image shows the style of retouch I have been aiming for. It is not finished, but in this raw state it illustrates these aspects well. T.B.C!

Hulme STEAM maker faire

Learning through making

On a sunny Saturday afternoon two weeks ago I was fortunate enough to run the above workshop at the Hulme STEAM maker faire in the garden of the Old Abbey Taphouse. Running this workshop in a pub is a double edged sword (so to speak). We had almost unlimited access to empty beer bottles. We also had almost unlimited access to full beer bottles. Health and safety issues aside, STEAM is an acronym for Science, Technology, Engineering, Arts and Maths and the thrust of the event was to explore how the Arts and Sciences overlap. We had three hours and I ran two consecutive sessions with a fair degree of overlap. My overall aim was to introduce people to the complexity of an apparently ‘primitive’ technology through the process of making a Bronze Age arrowhead. The session was successful on a number of levels!

First of all both sessions were well attended, and it is therefore reassuring that other people also find these things interesting, and it is not just me. It was really rewarding being able to share my enthusiasm (obsession).

Secondly, it was open to everyone and so two younger knappers were able to take part. I was surprised (although I have no idea why I should have been) at the degree of concentration and their results. This opens up the whole area of at what age in the past children started knapping?

Thirdly, everyone seemed to get something from it and some people made really good arrowheads, fantastic examples for first attempts. We also had some interesting discussions about the different effects of the different tools, and on a personal level I can now clearly hear when someone is hitting the glass incorrectly.

Everyone seemed to love the initial stage of removing the beer bottle base using a nail and cork, and because the session overall was an enjoyable and engaging experience I was awarded £200 seed corn funding to develop the workshop. And as I have already said, it was sunny!


Many thanks to Jana Wendler and Sam Illingworth for organising a brilliant event, and Ellie Mycock for taking the great photographs. Also, please check out this link: Hulme STEAM maker faire to see the other great ideas and innovative projects exploring this art and science overlap. My thanks to Hannah Cobb in the University of Manchester Archaeology Department for the loan of the safety goggles.

A second point from the second preform.

9.6.17 1

I was more cautious with this one and it turned out longer. I tried to stick to my method, ventral first, then dorsal, then the point, however the angle of the edge face made me improvise a bit. I am pleased with the needle like point, and am going to arrange to go back into the Manchester Museum to compare and contrast. I think the key difference between mine and the actual points may be thickness and edge angle. Let’s see. 9-6-17-2.jpg

The next post will be about home made pressure flaking tools, as we have been innovating in our twice weekly knapping get-togethers.

Period bottle glass number two

This is one half of a piece of period bottle glass recovered from Chorlton Ees. My aim this time was to make a larger point and maintain some of the lettering on the dorsal surface (see Foraging for early 20th Century glass and ceramics).  I used a glass cutter to score the inner concave ventral surface of the larger piece of glass, and then tapped the dorsal convex surace with a hard hammer. The large piece split cleanly into two useful preforms, one of which you see here. I then started to work on the ventral surface of the margins to produce a steep edge angle. This would allow me to flip it over and start using the newly created steep edge as a platform for penetrative flakes. The aim of this penetrative flaking was to flatten the convex curvature on the ventral face. I was able to straigten and steepen the margins but was not as systematic as I could have been. Working around a thick area semi-disaster struck! break.png

I called it a day in the lab and took both pieces home, and the following day finished it off. The ‘A’ is a useful landmark on all three photos and gives an insight into the degree of reduction. I am getting a feel for this thicker and uneven material and was able to avoid a large internal bubble, which is why the base has remained relatively unworked. The end result isapproximately 76x26x7mm and pretty well flattened on the ventral side.


After the above photograph was taken I serrated the margins. My main learning from this piece is to be systematic in my reduction sequence. If my edge steepening had been more consistent I would have achieved a longer point. I am making some points for Eleanor Casella’s teaching collection and I think this can be one of them as it has an interesting provenance and biography, as well as being an aestheically pleasing example.
