International
Seminaar of Bulat (Wootz) Crucible steel - 2012 BULAT
is a kind of steel, which was used for swords, knives and armor plating.
A sword made from Bulat has a good cutting edge, while not being so hard
it would break in battle when struck. Additionaly the steel has an
attractive pattern of microstructures, which are visible with the naked
eye. Europeans
came in contact with the sharp edges of these swords during the crusades,
where the crusaders discovered the superior abilities of Islamic weapons
made from this material. This
type of steel, also called Damask ,Wootz of crucible steel, was first
made in India by mixing iron together with carboneous matter from plants,
such as leaves or dried wood, in a crucible. This crucible was then
heated to melt the charge completely.
Steel was made in a similar way in Central asia (Turkmenistan and
Uzbekistan). In western Europe, everyone failed to recreate and forge
this steel. During the 19th century the secret of making and
forging this steel wad lost due to the rise of industrial steel
manufacturing. It is however evident that in the 19th century,
this type of steel was still being made in Tbilisi, Georgia. In
2010 we organized a seminar in Antwerp (Belgium) with a Bulat workshop.
This workshop was given by the Georgian metallurgist Dr. Zaqro
Nonikashvili. The workshop consisted of two days of Zaqro
demonstrating the technique, with theoretical and metallurgical
information. Due
to the good responses, we are delighted to know that Zaqro is prepared
to come to the Netherlands and Belgium again to share his knowledge and
unique methods. Atelier Gotscha Lagidse from Netherlands with
support from Klaas Remmen (University College of Antwerp) and others,
are planning to make a second ‘Bulat from Georgia’ seminaar in 2012. A report of last years workshop is accesable at www.gotscha.nl. Content
of the Symposium During the symposium there are readings on the subject, and it will be possible to share expieriences. There are several experts invited to the lectures. There will be a demonstration of the unique Georgian technique. During symposium contemporary works by Bulat / wootz be exhibities also exhibited ancient examples. Both
homemade crucibles and factory crucibles will be used in a coal fire and
a gas fired furnace. The solidified steel will be given heat treatments
and will be forged into a knifeblank, using special techniques to
manipulate the pattern. The obtained knive will be heat treated and
tested, it would have to scratch glass to pass the hardness test. The
pattern will be shown by grinding and etching the steel. During these
activities, there will be Dutch, French and English explanation of the
metallurgical events which occur during the forging and heating cycles.
The goal of this workshop will be learning the complete process, and
sharing the knowledge how to make Bulat steel. The motivated participant
will be able to make simple Bulat objects. The
symposium is of a non profict nature (for Organisators), only the costs will have to be
compensated for. We do want to compensate the Georgian Specialist for
his travel costs, accommodation expences, and teaching his technique.
The costs are set to 220 EUR per person. Registration
can be done by sending an email to info@gotscha.nl.
After registration, the participants will get a payment request. After
the payment is received, info will be sent with more information
concerning the program of the symposium, exact date and place. Please
ask questions only by email. Kind
regards Gotscha

A Report of Bulat workshop (November 2010) in Antwerp (Belgium)
Dr. Zaqro Nonikashvili studied in Medical Universiteit. He was first introduced to Bulat in Susdal (Russia) during his studie in known metallurgist Basov. Since 1995, he experiments with Bulat steel in Georgia and professionally employed as a metallurgist specializing in Bulat. So far he has more than 900 smelting process.
