Dr Rangi Te Kanawa is a textile conservator at the Museum of New Zealand Te Papa Tongarewa. She uses her knowledge of traditional dyeing practices, science and scientific experimentation to preserve fibres in textiles that have been dyed using iron-tannate black dyes.
This first-person narrative uses a family piupiu as the context to explore:
- traditional harakeke weaving and dyeing practices
- how scientists collaborate to find solutions
- the scientific process used to test their solution, including controlling for variables
- the need for evidence in science.
