An introduction to finds processing and conservation

By Lucie (Volunteer from the University of Lincoln)

I’m currently studying for a degree in Conservation of Cultural Heritage at the University of Lincoln and have just finished my second year. As part of the course I have to do a six week work placement to gain some experience of working in the world of conservation, and as I hope to specialise in archaeological conservation when I graduate, I chose to come to Allen Archaeology. This seemed like a perfect opportunity to not only see how a commercial archaeology company works but also to get some hands-on experience.

I’ve been working in the finds department, processing the finds which involves cleaning bags and bags of objects that have come from the various sites that the company are excavating. So far this has mostly comprised sherds of pottery and animal bones along with a few iron nails and pieces of ceramic building material (CBM). Once the finds are clean and dry they are marked and repackaged in labelled bags ready to be archived.

However, it’s not all been bits of broken pottery. I was lucky enough to be given a large Iron Age bowl to work on that had been excavated from one of the sites and was still encased in the clay soil from which it had come from. I carefully removed the soil layer by layer using various tools from my conservation tool kit to ensure there was nothing else within the soil and also to ensure that I didn’t cause any damage.

Details of the ‘slash-ware’ start to emerge!

Once as much of the soil as possible had been removed and the pot had had a chance to dry out a little I washed the remaining soil off it using a toothbrush and left it to dry thoroughly. After it had been cleaned there was a pattern visible on the outer surface which is apparently called slash-ware because it looks like it has been slashed. To be one of the first people to see it since it went into the ground is a real thrill and for me, part of the excitement of working with archaeological finds.

I’m really enjoying my time here, getting to be hands on with the finds is great and to be given objects that are thousands of years old to clean is a dream come true for me as this is a job I have wanted to do since I was young.

Find of the month: July – worked bone from Cambridgeshire

Lucie Evans, Branston Academy

Our find of the month for June is a collection of carved animal bones engraved with a ring and dot decoration. They were found on farm land located in South Cambridgeshire. The bones in question were found in the fill of an oven which has been dated to the Iron Age. It appears that a pit was later dug into the centre of the oven and objects discarded into it. The pit contained layers of silty and organic deposits and the four pieces of worked bone were found along two metal objects. The appearance of ridge and furrow cropmarks and an Iron Age enclosure ditch suggest an agricultural community having occupied this area.

Worked animal bone

There has been a bit of a debate within the office as to what the worked bones would have been used for. Whilst three look as if they were just used to practice the design of dot and ring on, one of them has has been shaped with a rounded end. They are all made of animal bone, not antler (which seems to be the preferred choice of the time). Three were crafted from long bone while the rounded end piece is made of metapodial (long bones found in the hands and feet of mammals which connect the digits to the centres).

One suggestion of what they may have been turned into is a comb beater which would have been used to push down ‘weft threads’ when weaving.

The ring and dot pattern can be found on objects from pottery to bone; it is used nationwide and across the centuries. The ring and dot pattern would have been created with an Iron Age compass tool, which helped to create the perfect circles. This simple design would has been described as ‘folk art’ as it would have been simply used to make the piece more interesting.

I find these pieces really interesting as to me it shows the gradual skill learning and perfecting taking place, and although it is most probably down to my imagination I see these as the slow progression of an ‘individual’ in their craftsmanship.

Find of the Month: An Iron Age loom weight

Our find of the month for May enables us to have a look at textile production during the Iron Age. It is a large, triangular loom weight which was found during an evaluation in the village of Kirkby on Bain, Lincolnshire. Archaeological evidence for the actual process of textile production is scarce as the wooden looms and associated threads and wool don’t survive. What do survive better are the spindle whorls from the spinning process and loom weights from weaving.

Loomweight

These triangular shaped loom weights are thought to have been used during the Iron Age and are usually made from fired clay, though stone is common on earlier sites. The clay is normally of low firing and as such the weights are prone to break. Later Anglo Saxon loom weights are circular and many Roman ones are pyramidal in shape. The reason for choosing a particular shape is not known and is likely a personal or cultural preference. Loom weights are a fairly common find on sites in Northern Europe and in the Near East where a certain type of loom was used.

The loom which would have been in use during the British Iron Age was the warp-weighted loom which became obsolete in the Roman period but had been in use since the Neolithic. This was a fairly simple loom which consisted of two wooden uprights and a horizontal bar, which would rest against the wall. The warp (vertical) threads would hang freely from the bar and would be tied individually or in bundles to the loom weights. The clay loom weights hanging from the bottom of the threads would keep them taut enough to enable the weft (horizontal) threads to be more easily passed over and under in the weaving process.

This particular loom weight is quite large, weighing in at 2.27kg which would create quite a bit of tension in the yarns. As mentioned earlier, due to the low firing of the clay, they can break fairly easily and several of these heavy items hitting into each other as you weave would cause frequent damage. This loom weight has lost the tips of two of the corners but is still a remarkably complete example of the type.

Running a large scale excavation

Dan Connor, Project Supervisor

In this blog I have been asked to try and describe what my experience running a large scale excavation was like. I have been a supervisor at Allen Archaeology since November 2014 and have worked here since October 2013. Prior to working at Market Harborough I ran several evaluation trenching sites, some open area excavations and helped supervise the large-scale North Killingholme site under the direction of Chris Casswell in the summer of 2015; this would be the largest site I have coordinated.

So, a quick description of the site, Market Harborough was an agricultural field, about 5.5 hectares in size that underwent a strip map and record, during the summer of 2016. This was done as a condition of planning consent to allow the building of over 100 houses on the site. Prior to us starting work the site a geophysical survey and evaluation trenching had been undertaken. This meant that there were known archaeological remains on the site consisting of field boundaries and enclosures, that were shown clearly on the geophysics. The nature of these results suggested that this site would have a mix of Romano-British field systems and some earlier Iron Age features.

The geophysics results for the site

Machines started opening the site up in early March, and after a few teething issues we were largely ready to go.

One of the excavated ditches

It was daunting at first, a large tangle of intercutting ditches and discrete features over an area the size of four football fields; but breaking it down made it much easier to grasp. In the end I decided to have the team work through the site in a large group, breaking the site down into distinct parts and moving from one area to the next. It often feels like Roman archaeology leads itself to this approach as Romans loved squares and enclosures and like to keep things surrounded by big ditches. Difficulties arose however with the Romans love of maintaining said big ditches, then leaving them, before digging new ditches in exactly the same place. This results in features having multiple re-cuts and phases, and the key was to try and link these phases together. This is what makes Roman sites fascinating; distinct phases of activity and occupation can be observed, and in this case it emerged that there were five clear phases of activity, despite the complexity in the features.

The earliest period of occupation recorded on the site dated from the early Neolithic, with several pits that contained worked flint including a fragment of a leaf shaped arrowhead, and a piece of a Langdale stone axe in the northwest corner of the site. A prehistoric pit alignment was found oriented north to south and is similar to others found in Leicestershire. Also recorded were the remains of at least two Iron age drip gullies associated with round houses.

The majority of the site was, as expected, Romano-British field systems and enclosures. We had a number of stand out finds from this period including a partial sliver ring, a copper alloy make up tool, a brooch and multiple quern stones including a rotary and saddle quern.

However there was not just the archaeology to consider, a large-scale project like this meant public interest, I had had a little experience with this working at North Killingholme, but this was my first experience of being directly involved. An open day was organised and volunteer groups from local historical societies were invited to work a few days.

On the open day, just over 70 people turned up for a site tour and to look at some of the material we had found. I found that while people enjoyed their time most were expecting more of a traditional/research archaeological site and less of a “construction” image. I imagine not looking like a university professor did not match many people’s expectations, neither did the hard hats and high visibility vests everyone was wearing. Regardless many local people had real enthusiasm about the work we were doing and a genuine interest in the artefacts. Many were eager to add their own interpretations to what we had found and what could have been there.

Volunteers from local historical societies were invited to come onto site and excavate some of the features, specifically some of the pits in the pit alignment. A big difference that the volunteers noted themselves was the amount of work and the speed it was expected to be done at. It is a long time since my university field schools and I have only worked on commercial archaeological sites since, so having volunteers was a bit of an unknown quantity. I enjoyed having them on site though and I believe they learnt a bit about what digging for a company was like and the benefits of doing volunteer work.

Most people were working away from home on this job and that can be stressful. We seemed to avoid this, and I think it was because people got along socially as well as at work. Cooking together in the evening, playing board games and *a couple* of beers in the evening helped pass the time and brought people together. It created a good atmosphere and I felt everyone was enjoying working on the site.

Over 580 holes were excavated, over 3100 context numbers assigned and just under 1200 drawings were completed to investigate this part of a Romano-British settlement. It was a great site to work on; archaeologically it was interesting fitting the development of the site together alongside some nice finds, with evidence of extended occupation from the Neolithic to the 4th century AD. The group of people working on site really pulled it together. It made running what could have been a very stressful and complex site straight forward for me and resulted in a site I have found fascinating to record.

The team working hard

Lubenham Hill Guided Tours

Over the last couple of months we have had staff working on an excavation at Lubenham Hill, Market Harborough, in advance of a residential development by Linden Homes. On Thursday 28th July 2016 we are opening the site to three guided tours at 10am, 12 noon and 2pm. More information about the project can be found here.

There is no parking on site and therefore access is strictly from the footpath that runs through the site from ‘The Pastures’ on Brookfield Road.

Site access for visitors

Hello World

Welcome to the first Allen Archaeology blog! We are going to be posting every Friday afternoon little bits and pieces for people to enjoy in their tea breaks. These blogs are going to include exciting things that are going on at the company, profiles of our staff, stories from some of our sites and the things that we do as a commercial unit.

The blogs will give you the chance to hear from staff across the company, from our Trainees to the Directors, and to find out about what it is like to be an archaeologist from the people who are, quite literally, on the ground. We hope to start a conversation about what’s going on in the commercial world, at Allen Archaeology and further afield, so please engage with us!

If you’ve not visited us before why not have a click around our fancy new website and check out who we are and what we do! If you have found your way here then here are some pictures of what we’ve been getting up to this week.
