In 2022 a team led by Mark Jackson and Richard Carlton (Newcastle University) with Dr Mirsad Sijaric (Zemaljski Muzej, Sarajevo, Bosnia) documented endangered material knowledge related to traditional pottery-making in Bosnia-Herzegovina. The roots of these traditions can be traced archaeologically to the early medieval period in the Western and Eastern Balkans between south-east Slovenia and northern Albania. These traditions have declined from over 100 centres and thousands of potters in 1900 to only four locations in Bosnia-Herzegovina. These traditions display wide variation, typified by use of hand-wheels and forming techniques focussing on coil-building and coil-throwing, as well as open-firing in bonfires or single-chambered kilns.
