<p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125);">Thanks Alice. As Anne says, the wear on the horn
comb teeth is at a different location. Your pictures of bone, antler and
ivory comb tooth wear are more what I am used to seeing. Marloes has had
lots of horn combs and I don’t remember wear down at the bottom of the teeth
like that on hers (please do correct me Marloes if I am wrong), so perhaps the
way the comb is being used here is an important factor. </span></p>

<p class="MsoNormal" style="margin-bottom: 12pt;">Dear Sonia and other comb enthusiasts,<br>
I am sending images of a VERY worn ivory comb from Visegrad that
I suspect was used frist by a Hungagarian owner and then for genration by the
'new' Ottoman owners. Thee is als oan example of wear on a 15 year old bone
comb that used to belon to a friend of mine who used it everyday, twice a day
with long hair, a less used but still quite worn ivory late medieval comb
from Buda and a quite worn antler comb from a AD 3rd c. Sarmation settlement.
Enjoy!<br>

<p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125);">Horn is formed from layers (visible in
Alice’s photo) of finely corrugated sheets of mineral stiffened keratin
protein. Working of the surface of the comb exposes these layers at the sides
and edges of the teeth. If these layers wear at different rates (perhaps due to
differences in mineralisation or organisation of the protein matrix) this will
produce slight grooves in the surfaces of the comb teeth were the more readily
worn layers are exposed. Once these grooves are formed the hair will
catch in them, increasing the wear at these points. As the grooves get
more pronounced more fibres will get funnelled into them as the comb is pulled
thought the hair, increasing the wear still further at these points (even into
more resistant layers of the horn) eventually causing the
‘beading’. </span></p>

<p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125);">Bone and antler are more heavily
mineralised than horn, their organic component is collagen rather than keratin,
and their structures are entirely different to horn. In addition, the physical
properties and structure of bone compact tissue are different to those of
antler. So although the mechanism of wear (abrasion by hair/grease/dirt
combination) is the same, the ‘necking’ or ‘beading’
produced should be different in detail in these different materials. Has
anyone observed this or done any experimental work in this area?</span></p>

<p class="MsoNormal" style="margin-bottom: 12pt;">One
thingI can say that the notching or beading on bone/antler/horn/ivory combs
seems to start seriously developing after ten years. I have an example of
daily use by a single individual (I will send you my comb article) with
long hair who used the comb (bone) primarily to clean her hair of grit after a
day in the fields. Her family had another comb (this one of horn) which was
used for similar purposes by everyone in the family for about 20 years and then
by the mother alone for another 20 before being put away. That one has very
pronounced 'beading' on it. I think the lesson to draw is that specialists have
seriously underestimated the length of time such objects were used in the past.
If I forget to send my article remind me.<br>

Does anyone on the list know of any studies of how quickly the<br>
teeth of bone or antler toilet combs may become beaded? And might<br>
the way hair was treated make a difference to the extent of wear?<br>
Sorry if this is a perennial question, I only just joined!<br>
