Activity taking place as part of the European Heritage Days 2017 celebrations. Educational Service of the Angra do Heroísmo Museum, 23 September, 10:30 a.m. to 12:30 p.m.; 2:00 p.m. to 5:00 p.m. Dyeing is a chemical process that changes the colour of textile fibres through the use of dyes and the application of mordants that fix them. Time-consuming and complex, given the multitude of variables involved, the art of dyeing is also extremely fascinating when approached from a craft perspective, as it allows a new look at the many raw materials available in nature and facilitates a rediscovery of ancestral techniques and knowledge. In this workshop, we will recall the importance of the export of woad and madder in the Azorean economy in the 15th and 16th centuries, explain the basic principles of traditional dyeing with vegetable dyes, and carry out dyeing with dye plants, using different natural fibres. Trainer: Guida Fonseca. Participation is free, but limited to 15 adult participants. Registration by telephone on 295 240 800 or by email at [email protected].
