Precision drawings made fast with lasers

Peter Demján

Understanding the development of pottery shapes and forms plays an important role in reconstructing ancient living and making. Each fragment has to be carefully studied and precisely documented, including a drawing reconstruction of the original vessel based on the profile and estimated diameter. This process is usually quite time-consuming and involves either drawing by hand or creating a digital drawing based on a 3D scan.

During this season of the Kaymakçı Archaeological Project, the pottery processing team got new reinforcement in the form of a prototype Laser Aided Profiler (LAP), developed specifically for measuring the profiles and circumferences of pottery fragments.

The Profiler enables us to produce a high-quality digital drawing of a ceramic vessel based on a fragment in a matter of minutes. Such drawings can then be used to analyze various vessel types in traditional ways or to compare the shapes of profiles digitally and calculate their similarity. This process, called morphometrics, enables us to analyze thousands of fragments from different parts of the site, or even different sites, without having to go over every single one by hand.

So many sherds, so little time: re-analyzing pottery at Kaymakçı

During the 2017 study season, the pottery team at Kaymakçı is re-examining the great amount of ceramic sherds collected in previous years. These have already been processed during the excavation seasons, but this year the goal is to analyze the pottery repertoire in more detail by looking for major groups and subgroups’ distinctions and correcting possible errors. This detailed study will allow a more careful assessment of intra-site variation and represents a pivotal element for the interpretation of the excavated contexts.

We follow the now well-established processing procedures. Every group of sherds collected from a context is divided into sub-groups according to fabric and typology, while diagnostic specimens (rims, handles, bases) are numbered and recorded separately.

  • Photographing a sample of ceramics.
  • Measuring color with the CAPSURE.

 

 

 

 

 

 

 

 

 

 

 

All sherds have now been photographed and weighed. Additionally, the color of the interior and exterior surface is recorded using Pantone CAPSURE devices. Sherds of interest are also analyzed via 3D scanning. 

Making a 3D model.

The process requires teamwork and coordination, and we are lucky to have extra help sometimes!

An exchange

Christina Luke

Last week, the Kaymakçı Archaeological Project (KAP) and the Fen Bilimleri School in Salihli had the opportunity to spend the day together. After tea, fresh apricots and homemade pastries, the students were split into three groups.

  • Project and school leadership meet.
  • Beautiful apricots from the Şener's garden.

 

In the ceramic lab, they were shown recording methods and 3D scanning. In the conservation lab, students learned about objects and science, and they tried to mend broken plates (from the local department store Kipa). It was hard!

In the zooarchaeology lab, they discussed the details of studying bones from the archaeological record to understand food patterns but also arts – wool and leather especially. KAP team members introduced students to using 3D images and virtual reality to determine the difference between sheep and goat bones.

In the afternoon, KAP members visited the school in Salihli. During a lovely poolside lunch, we met the director and talked with teachers and students about their school and future collaborations with KAP. We were impressed by their English and felt ashamed that we didn’t speak more Turkish!  

 

We were then shown the lower school, including the terrific chess room. We toured the main building to see classrooms as well as the wonderful café on the upper floor. Our time ended with a visit to the horses. We learned that this part of the curriculum promotes civil engagement and appreciation of animals.

Planted in Istanbul

Nami Shin

A beautiful day at Koç.

Analyzing ancient plant material is extremely rewarding, but can be a laborious process as well. A single archaeobotanical sample can take anywhere from a couple of hours to days to finish. However, being on the beautiful campus of Koç University makes the analysis just a bit easier. A beautiful forest surrounds the university and the various plants that decorate the campus are all labeled with their scientific names. As an archaeobotanist, the abundance of nature is calming to me and the labeling of the plants is something I truly appreciate.

 

 

 

My time at Koç this year has mostly been spent analyzing the botanical samples from the 2016 excavation season. The analyses have proven fruitful and I have found many exciting things in the samples. For more information, look out for future publications!

Appreciating the fact that all the plants are labeled.

Analyzing these samples is extremely important in understanding what life was like at Kaymakçı during the Bronze Age. At Kaymakçı we know they were eating barley, different varieties of wheat, grape, and different legumes among other things. Looking at the past through plant remains not only gives us an idea of what they were eating, but also the other types of plants that dotted the landscape of the site. We can see what kinds of flowers and other wild plants were present, giving us a richer picture of what life looked like for the ancient inhabitants.

As the excavation continues, our knowledge of the ancient environment will also continue to grow. I look forward to learning more about these ancient people and I hope you do too!

The garden. One of the most beautiful places on the Koç campus.

Holding the Past

People in the past used pottery in many aspects of their lives, but especially during meals. As we excavate each day at Kaymakçı, we uncover these vessels, broken into pieces and scattered throughout the site. Many of these vessels are bowls, useful for multiple purposes during meals.

As we work with these vessels, we have the chance to touch and hold them as people did in the past. Handles on the sides of the bowls still fit well in our own hands.

Even though the vessels are usually broken, we can imagine how they would have looked when complete, in the past. In this way, we connect with the people who lived thousands of years ago based on our shared human activities of eating and drinking.

Floating at Kaymakçi

Emily Johnson

So, what does it take to transform bags of unremarkable soil samples into analyzable carbonized material? At the Kaymakçi Archaeological Project, this involves a large orange flotation tank and a lot of water pressure.

In order to deliver water to the tank so that we can dissolve the soil and leave the carbonized remains floating on the surface of the water, an electric-powered pump pushes water up a hill to a repository, where it then flows back down the hill. The floatation team is able to take advantage of the water pressure both as it is being pushed up the hill and as it is falling back down in order to help release stubborn carbonized plant and seed parts from the soil.

Of course, this often involves a bit of troubleshooting, including building a series of canals to divert water flow, dealing with temperamental hoses and valves, and managing the local wildlife.

In the end, the carbonized remains that are analyzed during the off-season are invaluable in helping the project to understand the life and environment of the people living at Kaymakçi.

Newcomers at Kaymakçı!

Haley Chasteene and József Puskás

Newcomers to an archaeological project usually have a period of adjustment. Luckily, here at Kaymakçı, a fast-paced learning environment and very friendly team and staff can help alleviate newbie stress. Haley is a recent graduate from San Diego State University and has a background in the archaeology of California. Joska received a MA degree from BBU from Cluj-Napoca, Romania, and has experience in excavating Bronze Age sites in Transylvania. We both decided to join this project to widen our knowledge of digital archaeological technologies and to experience a new environment.

Teamwork: Haley Chasteene recording coordinates with the RTK GPS, while Joska Puskas holds digital photogrammetry target in place.

What happens when you don’t excavate for two years? – reviewing excavation area protection measures

Caitlin R. O’Grady

Every season, we spend a lot of time and effort implementing measures to protect excavation areas between field seasons. This includes “wrapping” architecture, scarps and baulks with geotextile, a water permeable cloth made from thermally bonded non-woven polypropylene fibers. The geotextile protects these features minimizing erosion and plant growth. Following wrapping, we use rocks and “dirt bags” to ensure complete protection.

However, long term exposure to plants, animals and the elements between seasons cause the geotextile to degrade, which makes it necessary to “unwrap” and “rewrap” architecture and excavation areas.

Luckily, I work with a great team of people that make this process smooth – even on the two hottest days of the season! 46° and 47° C (that’s 115° and 117° F!) thus far.

In anticipation of this process, the conservation team unrolled geotextile to cut more manageable pieces to use in the field.

Going 3D at Koç

Tunç Kaner

 

 

During my two years with the Kaymakçı Archeological Project (KAP), I have worked closely with Peter Cobb to develop a holistic recording system for ceramics from Kaymakçı. Related to this work, I have also recently begun to help with the 3D digital recording of ceramics from the Central Lydia Archaeological Survey (CLAS), directed by Christina and Chris between 2005 and 2014.

I live and study in Izmir at Ege University, but I travelled to Istanbul a few times during the 2015–2016 academic year to work with the CLAS material in the Archaeology Lab at Koc University. I worked with Christina Luke and Chris Roosevelt in person, and Peter Cobb virtually, to train a team of MA and PhD students in 3D recording methods. I also set-up the project’s NextEngine 3D Scanner as well as photography and Pantone Capsure (Munsell) stations in the lab, where they will be set up again in the fall for the next academic year. The training took two weeks; later I monitored Koç students from Izmir and visited Istanbul again for intensive periods of work.

We are continuing the same procedures now in our field lab, where we are working with a larger team on classifying and documenting ceramics that have just been excavated.
