History of Dyes: from Ancient Egypt to Modern Times
Dyes have been used since ancient times to colour fabrics, but more recently dyes are also employed for technical as well as aesthetic applications. This talk will highlight the most important natural dyes, including some that could only be worn by nobility; then look at the invention of synthetic dyes which led to brightly coloured fabrics becoming widely available. As well as for fashion, dyes today can be also designed for functional uses and some of these high-tech applications will be mentioned.
Christine Holdstock, a Chemistry graduate from the University of Sheffield, became involved in the area of colour when she joined the Dyeing department of Wira (the Wool Industries Research Association) in Leeds. At Wira she undertook research into the control of the dyeing process, and was awarded a PhD from the University of Leeds. Christine was a member of the Department of Colour Chemistry and Dyeing (which became the Department of Colour Science) at the University of Leeds for over 20 years. She taught many aspects of Colour Science, including the history of coloration, human colour vision, colour measurement and dyeing. Christine was awarded the Society of Dyers and Colourist’s Silver medal in 2014. Having retired from the University in 2016 Christine is now a Colour Science Consultant.
You do not need to already have the free version of Zoom to be able to take part as Zoom will connect you to the platform remotely. There is no need to have a webcam or a microphone as the audience will be asked to turn off their video and mute themselves to avoid any possible complications. Questions for the speaker should be posted via the chat function on Zoom during the meeting rather than at the end.
Future webinars are being planned for the third Tuesdays of each month at 2 pm (London time). The topics will include the history of the use of radium in medicine and astrochemistry.
