This research will focus on Conste des Ververs a unique and rather unknown Flemish dyers manuscript kept in the archives of Leuven. Dated 1619-1623 and written by Henricus Coghen a dyer who lived and worked in Leuven. Wool silk, linen and feathers were the materials to be dyed. Human and natural sciences will be involved unravelling the research on the origin of the dyeing techniques used in early seventeenth century in Brabant, Leuven. In order to better understand the used techniques, ingredients and materiality. The manuscript will be transcribed and the historical recipes will be reconstructed. This project focusses on the origins and dyeing techniques used in the manuscript. Relations between the manuscript Conste des Ververs and an existing recipe corpus from fifteenth to seventeenth European recipes books will be explored. This will enable to shed a light on the circulation of knowledge in the written and printed historical recipes during the seventeenth century. Although a substantial part of this research will focus on the historical making processes and the partly forgotten source materials and techniques that were known by craftsman. This will be done by 're-working' the transcribed recipes from the manuscript Conste des Ververs. This research wants to generate and address salient research questions that would not have been raised by text-based analysis alone. The purpose of this study is to understand the process of making, and the partly forgotten source materials and techniques, by unravelling historical recipes and reconstruct them in order to understand technique and materiality. In addition this method of working develops a new methodology and procedure to study historical coloured textile materials.
