Abstract

The colourful embroidery of Castelo Branco (Portugal) was the theme for the development of a project that enhances the relationship between formal and non-formal contexts in chemistry education and in the training of teachers and cultural animators. The central question concerns the possibility of identifying and obtaining the old and modern dyes that are used for dyeing silk. We present two experimental activities: extraction of a natural dye and use of mordant with a synthetic dye.
