Fish skin and wool dyeing (fully booked)

Dye wool yarn and fish skins with Swedish native plants. Participants will take home samples of dyed yarn and fish skin. This workshop is led by Lotta Rahme (Lottas Garfveri) and Mirjam Åkerblom (Gröna Tråden)

Multiband imaging (few places left)

Participants will receive an introduction to multiband imaging with a focus on indigoid visualisation. The workshop will contain practical acquistion of images and discuss benefits and limitations. This workshop is led by Joanne Dyer (The British Museum)

Analysis of inorganic mordants and dye auxiliaries

This workshop gives an introduction to SEM-EDS (scanning electron microscopy energy dispersive spectroscopy) and XRF (X-ray fluorescence), as well as hands-on experience in using the different methods for the characterisation of inorganic components in dyed textiles. These workshops are led by Marei Hacke and Kaj Thuresson (Heritage Laboratory) with support from Amica Sundström and Maria Neijman (Historical Textiles).

Microfading and colour measurement

These workshops give an introduction to microfading and colour measurement using spectrophotometry. The participants will get hands-on experience of measurements on dyed textiles and blue wool standards. These workshops are led by Magnus Mårtensson and Elyse Canosa (Heritage Laboratory).

 

Guided tours

Visit to Gotlands Museum’s storage facility and Langska Huset.

This bus tour focuses on Tobias Lang, an 18th and 19th century printer and inventor. We will visit Gotlands Museum’s storage to see his original printing blocks and patterns and listen to a lecture by Lena Ideström about his work. Following this is a tour of Tobias Lang’s original house, now a historical building and café.

Guided walking tour of Visby

Join guide Mikael Norrby (Uppsala University, Campus Gotland) to learn about the fascinating history behind the Hanseatic Town of Visby, part of UNESCOs World Heritage List.

Guided tour of the Heritage Laboratory (no booking needed)

The Heritage Laboratory of the Swedish National Heritage Board is a central facility for the development and application of heritage science, including conservation science, archaeometry and art historical research.

 

Optional extra day: 14th October 2022

Join a 6 hour guided bus tour in the beautiful Gotlandic countryside. We will make stops at Högklint (one of Gotland’s highest seaside cliffs), stone ship burial sites from the Bronze Age, an historical fishing village, Mästerby medieval church, and Trådverk (a weaver’s workshop focusing on textiles dyed with natural materials). Lunch and a coffee break is included in the tour.

This is planned for the day after the conference and must be payed for separately. Please note that many of the stops are outdoors and weather on Gotland can be windy and rainy during October, so bring appropriate clothes and shoes. There may be some walking involved but nothing strenuous.
