Experimental production of stone tools

Large glass ovate handaxe

Glass, Handaxe

I don’t normally destroy perfectly functional things in order to make my stone tools, however…I found this nice thick glass ashtray in Oxfam and it reminded me of the glass slabs I want to produce with Nacho.

So £3.99 and 24 hours later I was sat in the lab with a small hard hammer. The glass was really good to work even if it took me a while to get rid of the ‘walls’ of the ashtray.

Like the older glass I am used to, this ashtray glass had bubbles in it. I knew what I wanted, a large ovate handaxe, and my earlier removals, when I had more material were better. I have some nice flakes that will be good for arrowheads at some point.

It looks half decent, is fully bifacially worked (no original surface left) and I have retained a good size. However, it is not my best. Harder to see from the pics is a step fracture ‘island’ on one face. I relaxed a little and went ‘intuitive’, which felt right, but failed to produce descent removals.

I was concentrating more on outcome than process, and in doing so stopped giving each removal the due consideration it deserved. By the time I realised I didn’t any longer have a good way in to remove the steps. If I really wanted to make it into something I like I would lose size, and it would end up like many of my smaller ones that are either made from smaller pieces, or like this, takes me lots of removals to get it ‘right’. Anyway, the hour in the lab was the thing. It’s been a while and it was great.

On holiday

Currently we are on a mini two week tour of southern Spain. A first highlight was the Archaeology Museum in Jerez.

And yesterday, an exhibition at the Centre for Contemporary Creation in Cordoba

However, most interesting was a small ceramics workshop in the centre of Cordoba. In there I bought for seven euros a small melted glass bottle.

I also had a good chat with the woman who made it, and she did her best to explain to me the necessary kiln timings for a successful glass melt.

Going to southern Spain was a last minute thing for me. I have tagged along with Karen and Roxanna, to make sure we get to spend some nice time together this summer. However, I have really been struck by how stimulating getting away, but also engaging with new places can be.

I am really excited about making some large bevelled glass slabs, that I can then use to knap some bigger handaxes of colour. I am super busy when I get back, but a visit to the bottle tip, and a session with Nacho and his kiln are now high on my agenda!

Thanks to Brosky and Maria for making us super welcome and spending their time showing us around Cordoba. We are so lucky to have good friends in great places.

Bottle tip ovate handaxe

This afternoon Roxanna, Bella and myself went to the bottle tip. I thought from the style of the earliest bottles it was 1940s material and this newspaper from the site indicates late 1930s.

I was looking for big pieces and at first thought this was a metal pan lid. It was very concave and so needed considerable reduction to get it flat, but apart from a couple of irritating step fractures the glass behaved really well.

I took a few risks with this, but well prepared platforms and well behaved material led to this nice and lumpy but symmetrical ovate. Roxanna is not as keen on the bottle tip as me so we went to a cafe afterwards, to have some daddy daughter time…on our phones 😐
