Natural dyes and its didactic usage for education and leisure time activities
 Hirnšálová, Jana ; Skýbová, Jana (advisor) ; Pavlasová, Lenka (referee)
The purpose of this study was to remember and recreate natural dyeing technique, which is almost forgotten these times. It is possible to find remains of this technique with pre-industrial nations or as a part of dyeing handicraft. By inventing artificial dyes, natural dyeing was blenched and it becomes just an activity of special interested groups. Theoretical part of thesis is dealing with history of dyeing, preparing all the materials used for dyeing and to be dyed and finally charts involving dyes, extracted from vegetables, ordered by gained colours. Main purpose of the study is to verify colour spectrum by using known technologies, than to prove effect of chemicals and finally finding didactic utilisation as a form of experiments. The last chapter contains several educational projects which were developed entirely for this theses. These projects were designed to be used since seventh-grades and they are particularly devoted to plants which are used for natural dyeing. All the methods and accomplishments are presented not only by text form, but by photographs as well.
