Composite Antler Comb with Case Based on Tenth Century Gotland Find

Composite Antler Comb with Case Based on Tenth Century Gotland Find

I entered this comb into the Glymm Mere Arts and Sciences Championship in December of 2015. I love this little comb! It’s the first comb that I have created with a case and any real ornamentation. Normally I base my pieces on finds from Birka but I loved the extant piece and wanted to try to replicate it.

Composite Antler Comb with Case Based on Tenth Century Gotland Find

HL Disa i Birkilundi

“Bronze ornaments have hitherto been valued most highly by archeologists because it is possible to trace their development with the least difficulty and so to detect contacts with alien folk. Who knows what the significance of other objects, for example combs, may be when they come to be studied.”

-Hjalmar Stolpe

I’ve always found everyday items very interesting and combs are a wonderful example. The tenth century combs found in Scandinavia are well crafted, often beautifully decorated tools that people carried everyday and many were buried with. Combs have been found with multiple materials used as rivets implying that they were repaired as opposed to being replaced. This is the same tool many people today will purchase cheaply and use a few times before discarding it.

Combs are one of the most common items found in graves. The style that I have based this piece on (straight pieces with line and circle dot decoration) are found primarily between 950 and 1000. Earlier combs were more rounded and their decoration was more ornate. This change was most likely due to an increase in the population of Scandinavia resulting in a higher demand for combs.

Original Gotland Comb

The extant piece that I based my work on was a small comb with a case found in Gotland. While looking into comb production in Gotland I discovered that there is little evidence of a resident comb maker in that area. In areas like Hedeby and Birka there is evidence of larger scale comb production in the form of large piles of antler pieces and incomplete tooth and connector plates. This most likely means that comb makers would create their pieces in one place a majority of the time and then travel to other areas with a lower demand and sell their work during the large seasonal markets. Most areas would not have had a high enough demand to support a resident comb maker.

According to research, combs with cases have only been found in male graves. Combs in female graves tend to be found around waist area and were most likely carried in a cloth or leather bag on the belt and not hung from the brooches. This comb would have most likely been a man’s comb in the tenth century. It would have been created in Hedeby or Birka and brought to Gotland to sell.

Materials

Antler

Most combs are made of either Red Deer or Elk antler. Red Deer is more commonly found in earlier period while Elk, which is more readily found in Scandinavia, is found in later period almost exclusively. This happened because the population growth meant that comb makers did not have to travel as far to support themselves and used the local sources of antler.Red Deer is easily distinguished from Elk due to remaining blood vessels that create a brown discoloration in the antler while Red Deer antler is solid white.

IMAG0363

Cut pieces of elk antler showing the distinctive discoloration

Most of the antler found in debris piles have been shed. This is indicated by the condition of the burrs, the large piece at the base of the antler where it connects to the skull. The burrs found in the debris piles have the rough look of shed antler rather than being cut from the skull. The sheds were most likely collected during moulting season and then purchased by comb makers.

My comb was created using elk antler shed. I chose elk because the piece was based on a tenth century comb and this was the most common material used. Elk also has a larger amount of usable material. The spongy core is smaller leaving a thicker outer core.

Rivets

Rivets used to connect the pieces of the comb were made of copper, bronze, or iron. I have chosen dead soft 14 gauge copper to use create my rivets. Rivets found have been between 1 and 2 mm thick and 14 gauge sits right in the middle of that thickness. I chose copper because iron and bronze are less readily available to me and copper is more easily worked.

Tools

I used a saw, hammer, rasp, files and clamps all which are tools similar to those found in period. I also used a bandsaw and a drum sander to cut out the basic pieces and get them to a workable size. I have hand cut and filed the pieces down to size by hand previously and was unable to do this with this piece due to time constraints.

Tools used in comb construction

A small drill was also used to drill the holes for the rivets. I did purchase a hand drill and attempted to use it but the drill bits were too small initially. When I found a way to use the small bits with the drill the drill was too heavy for the small bit and the bit broke. I was able to successfully drill a hole into my test antler before this happened.

Both eye and breathing protection were also used as it is not safe to work with antler without proper protection.

Process

Breaking down the Antler

I started by looking at my antler and deciding which areas would be best to work with. I chose to use the thicker areas of the antler where it split into multiple points. I thought this would give the largest areas of useable material. The pieces were then cut down to workable pieces using a bandsaw and then run through a drum sander to create a uniform thickness.

Antler pieces cut and sanded to uniform thickness

Basic Pieces

After my rough pieces were cut I needed to be sure that I had enough material to create my comb. I took measurements of the original and discovered it was much smaller than I had realized initially. The comb itself is just over 6cm long and 1.5cm wide. The total length of the entire piece is just roughly 10cm long and 2cm wide. I measured out all the pieces needed and added a little bit of extra in order to account for loss due to cutting and sawing.

IMG_0258

Pieces measured out and ready to be cut

The pieces were cut out of the antler with a small saw. I clamped them down to my workbench in order to have better control. Once the pieces were cut I placed them together to be sure they would fit properly. There were some inconsistencies that needed to be adjusted. I thinned out the side pieces of the case so they were more even and didn’t look overly large and filed down the front and back of the comb and the case to make them even.

Pieces of comb cut and ready to be put together

Putting it Together

I started with constructing the comb. I clamped the tooth plates in between the front and back pieces and drilled two small holes the size of my rivets through each plate. I used two rivets per plate because I wanted to be sure they were stable and it was consistent with the look of the extant comb.

My rivets were created by taking a piece of copper wire and clamping it into my vice. I then used my hammer to flatten the top of the wire to create the head. After the holes were drilled I pushed the rivets through. One of the holes was a bit small and the rivet became stuck halfway in. I had a moment of panic before I was able to remove it and widen the hole to place a new rivet.

Cutting the Teeth

Once the comb was riveted together I cut off the excess tooth plates and used the rasp and files to smooth the edges and shape the top. I also added a point to the bottom of the tooth plates to make it easier to taper later. I didn’t want to completely taper the tooth plates at this point because I didn’t want the case to be too loose.

I wanted to try something new in an attempt to create more consistency in my teeth. I found a wooden comb of similar size to the teeth that I wanted to create I clamped it into my vice with a piece of test antler behind it and tried to use it like a guide to keep my lines straight and consistent. Unfortunately it didn’t work very well. The teeth are so small that they move and because I couldn’t see my antler the cut became more inconsistent and teeth were cut off. I decided the best way to cut the teeth was to mark the lines on the comb and cut by hand. This worked relatively well. There were a few small adjustments that needed to be made but I am happy with how the teeth turned out. After the teeth were cut I used a file to created the points on the bottom of the teeth and each tooth was smoothed out.

Before and after cutting the teeth

Making the Case

When the basic comb was done I repeated the riveting steps with the case. I needed the comb mostly complete in order to be sure the case would fit snugly. I clamped the pieces of the case around the comb and drilled the holes for the rivets. After the rivets were applied I was very surprised at how snugly the comb fit into the case. I filed down the inside of the case a bit and tapered the teeth of the comb so that they comb now fits snugly but is not too difficult to remove.The case was now smoothed out using files and the end pieces were cut to the appropriate shape.

Decoration

The basic comb and case were complete but I wanted to add decoration. The extent piece had both lines and a circle dot pattern. I had done some simple line decoration on previous combs but not the circle dot design. I created a small tool in order to create a consistent circle dot pattern. I used one side of a pair of tweezers and using my files shaped it into the tool that I needed. I did some practice runs on some scrap antler and it worked very well.

I did not want to duplicate the pattern on the extant piece but used the same designs to create my own. I used my tool to create the circle dots and a combination of my saw and file to create and smooth the lines.

Completed comb and case and the Extant piece

Conclusion

I am very happy with my completed piece. The size initially surprised me but I love how small it is and with the teeth that short they are stronger and still work very well.

In the future I would like to continue to work on the consistency of my teeth and experiment with other styles of combs.

10th Century Composite Antler Comb Based on Finds at Birka

10th Century Composite Antler Comb Based on Finds at Birka

I want to include documentation for pieces that I’ve entered into competitions during the past year. This was a comb that I created based on 10th century combs from Birka, Sweden and entered into Dragon’s Mist Arts and Sciences Championship. This comb was created entirely by hand and I was very happy with how it turned out.

10th Century Composite Antler Comb Based on Finds at Birka

I find composite antler combs to be a very interesting area to study. I love that something as simple as a comb took so much work to create and was clearly highly valued. They could be simple or very ornate and were found all over Europe but particularly in Scandinavia.

Combs even when found in the same area vary greatly. It is rare to see two combs of the exact same shape and style. This is because every antler is different which makes composite combs almost impossible to exactly replicate. There is a slightly more unified look to the single piece combs but in that case you are working with a flat, large piece of antler which would be easier to keep consistent with.

Composite comb and single piece comb

I was surprised to discover just how common place combs were in Birka. I explored the excavated graves on the island by way of Historiska Museet’s website which gives you access to details and pictures of each grave site by type and location. What I found was that if a grave had any objects still visible, odds were you would also find at least a fragment of a comb. When looking further into the research of others I discovered that combs are the second most common item found in graves at Birka. This shows that nearly everyone carried or owned a comb regardless of status within the community.

Combs were also not something that everyone made. Piles of both tooth and connector plates have been found along with scraps of antler. This was a specialized craft in the community.

Materials

Antler

Initially I believed that Red Deer antler was the primary material used for creating composite combs however after further research it seems that Elk was actually used much more frequently in Birka than Red Deer. Cow bone and Moose were also used but much less common than the above materials and were most often used for single piece comb. My piece was made using Elk antler as it is much easier to acquire than Red Deer and is the more common material used in my primary location of interest.

Wire

Material used for rivets is commonly said to be either iron or bronze. I do not have easy access to either and so decided to look further into copper wire as it is a material that would have also been found in the area (if you have bronze you have copper.) I found an article written by Niklas Stjerna regarding the analysis of wire used in composite comb making specifically in Birka in the tenth century. The analysis showed that the wire tested was almost exclusively nonalloyed copper wire.

The wire that I used was a 14 gauge dead soft copper wire. I chose 14 gauge (1.63 mm) because it sits right in the middle of the 1-2 mm diameter size that was commonly found in Stjerna’s study and it seemed like a large enough diameter to effectively hold the comb together.

Tools

I used a saw, hammer, various files, jeweler’s saw, and a rivet forming tool all of which were similar to tools found in period. I also used a drill to create the holes for the rivets as I did not have access to a hand drill at the time of construction.

Process

Experimentation

As it had been several years since I had attempted to make a composite comb I decided to start by making a practice piece out of wood. I used a large dowel and cut it down into plates like I would antler. The wood was very frustrating to work with as the grain tends to make it more unpredictable and it split and broke much more easily than wood. Since wood is also much softer than antler when I attempted to put together the comb using my copper rivets it looked very messy as the wire ended up bent over instead of having a head. This was a very frustrating experience and I don’t think I will be using wood to test antler work again!

The breakdown of the wooden “antler” and my resulting attempt at a composite comb from the pieces.

Before I began cutting down the antler that I intended to use for this project I wanted to try something that I had seen regarding the splitting of antler. Ambrosiani had speculated that the tine of the antler was used to split the larger section into smaller pieces. This seemed like an interesting thing to test as I had an extra antler that had been more weathered and was not in decent condition to use for actual comb construction. I scored the large piece of antler and attempted to split it using the tine. The antler split to some degree but not where is had been scored and the spongy inner core of the antler simply absorbed the tine.

An illustration of Ambrosiani’s theory and my attempt at splitting the antler with the tine.

Based on what I saw in this experiment, I do not believe that this would be an effective way to split an antler, particularly if you are expecting to use the pieces for something like a comb. Even if you could get the tine to split the antler the edges of the split would be rough and messy and there would be much more waste than if you simply cut the antler with the saw that you need to score it in the first place. I would like to test again in the future by making my cuts a bit deeper to see if that makes a difference on how clean the split is. It is also possible that the age of the antler affected the density of the antler’s core. This may have also created a less dense core that did not create enough pressure on surface of the antler to split it correctly.

Breaking Down the Antler

The antler that I had was a good size and so I had a lot of options in finding good areas to work with. I chose an area where the antler split to create the plates used for the teeth because it gave a wide and relatively flat spot to work with. This would create less waste and a stronger plate as you would be using less of the soft center of the antler. I used the saw to cut plates off the antler and shape them. I also filed them down to a uniform width so that they would hold evenly between the connecting plates. I left them longer than the finished comb intentionally so that I would have more space to work when I put the comb together.

The creation of the plates used for the teeth of the comb.

Initially I planned on using a piece from the large section of the antler to form the top connecting plates, however, I found an area on one of the smaller tines that I felt would work better. To create the connecting plates I took this section and cut it in half. The back area was fairly flat and so I cut it in half again and used a file remove the inside and flatten out the back of the plates. I used the saw to adjust the two pieces so that they were uniform and would hold the larger plates well.

Rivets

The creation of rivets is something that I have very little experience with. I looked at possible ways that it was done in period and decided to create a basic rivet using a metal tool to form the first head and then close the rivet on the piece itself. I created a simple tool for forming the first head. I used a block of aluminum (that was what I had available) and drilled two small holes roughly the size that I wanted the rivets to be. This worked relatively well with the exception of putting a piece in the smaller hole that was a bit too short and getting it stuck. If I were to create a tool for this use in the future I would run the whole the entire way through the block or split it down the center and clamp it together.

I had some difficulty forming the heads using the copper wire. They were forming off to the side and the heads were larger than I would have liked. I was working with a half-hard copper wire which made it very difficult to create a head at all. Once I moved to dead soft wire the rivets were easier to form. In the future I plan to experiment with heating the copper to create a more uniform head.

Simple riveting tool and copper rivets

Putting It Together

Once I had my plates and rivets I used clamps to hold the plates together in the desired configuration. I drilled holes though all of the plates and added the rivets. This part is simple to accomplish as long as all of your pieces fit relatively well together. If you have inconsistency in your tooth plates they can slip and cause the holes to be off (I had this happen with the wooden test comb.)

I used five rivets to put the comb together. The amount of rivets in extant pieces varies widely. I have seen combs with as many as ten rivets and combs with as little as three. I initially used three but decided that five would better hold the plates in place. The plates were able to move just slightly and I wanted the piece to hold together well.

Through my research I found that the majority of combs had relatively small connecting plates and teeth that were around double that size. Since the connecting plates are 1 cm I cut the area for the teeth down to roughly 2.5 cm. This gave the comb a much more accurate look and will give the teeth added strength.

Putting the comb together

Teeth

Extent combs teeth also widely vary. A majority of combs have very clear saw marks on the connecting plates which shows that the teeth were added after they were put together. This made the most sense to me as it gives you added stability when you are working as well as more consistency in appearance from plate to plate.

The extant combs have anywhere from 5 to 24 teeth per inch. My previous comb had 6 teeth per inch. Using the jeweler’s saw I was able to get 10 teeth per inch leaving .5 cm on either side. I marked the cut lines onto the plates and cut the teeth without a guide. I felt more confident about cutting them freehand because I was afraid that a guide may become crooked and I wouldn’t be able to see that there was an issue. I did have some issue with having my cuts stay completely straight because the jewelers saw has such a small blade. I plan to use a wider bladed saw on my next comb.

Cutting the teeth

There were a few issues with the teeth. The lines were very crooked and the space between each tooth was too small to actually brush your hair with. The teeth were also the same with all the way down when there really should be a taper, also to ease in combing. The solution to each of these problems was files! I found a picture of the tooth of an unfinished comb and it looked very similar to what I had created. This made me feel a little less like I had made a mistake and more like I was on the right track.

I first used a large flat file to taper the teeth. When you see side views of combs they generally have a trapezoidal shape from the connector plate down to the bottom of the teeth. To get this look I simply angled my filing, taking turns on each side of the plates, until the side view looked correct.

Before and after side views and the side view of an extent comb

The shaping of the teeth took a good amount of time. I took a small round file and shaped each tooth individually making sure to create a nice point at the bottom. This process eliminated the crooked look of the teeth almost entirely. I was amazed at how much of a difference it made!

Decoration

After looking at the finds from Birka I discovered that most were very lightly decorated. The piece that I based my comb on had no decoration at all but I wanted to add something as my previous comb had no decoration as well. I went with a basic line design as opposed to adding dots because I found more combs excavated from Birka with simple line designs. The design was made using a combination of a saw and file.

Though every composite comb is different almost all of them have a curved top. I had initially decided to leave my piece straight but after further research I went with a curve as well. This meant more filing. I shaped the top with a rougher file and finished the shaping with a finer one.

Conclusion

I am very happy with the final product. I have received great feedback from everyone who has tried it! The next time I would love to try a longer or double sided comb with two different sized teeth. I would also like to experiment further into decoration, possibly adding dots or additional shaping to the top.
