Dyes in History and Archaeology 41

This Special Issue features contributions from the conference DHA41. Dyes in History and Archaeology (DHA) is an annual international conference that focuses on the academic discussion of dyes and organic pigments which have been used in the past. Every year since 1982, this meeting has drawn together conservators; curators; (technical) art historians; craftspeople; artists; independent scholars; and scientists and academics from museums, universities, research centers and other public or private institutions. Their common interest is to delve deeply into the history, production, application, and properties of organic colorants, as well as their analytical characterization and identification, often in textile objects, but also in other substrates as well as painted surfaces. In the autumn of 2022, the 41st DHA conference was hosted by the Swedish National Heritage Board in Visby. This was the first DHA conference held in Scandinavia, and it attracted over 50 in-person participants, 70% of whom travelled from other countries to attend this conference on the beautiful island of Gotland. During the morning sessions of the three-day conference, the attendants in Visby had the opportunity to participate in workshops, tours, and activities. The afternoons were reserved for the scientific conference sessions, with all lectures broadcasted live and over 650 online participants. The book of abstracts is published on the DiVA portal (Digitala Vetenskapliga Arkivet), and many of the presented posters are available for download from the conference program. We are very grateful to the authors of the following 16 articles in this Special Issue for submitting their manuscripts and allowing us to put together a publication that presents the fascinating breadth of research into Dyes in History and Archaeology.
