Lather, rinse, and repeat – an insight into early chemistry. In this month’s episode of #FinallyFriday we dive into the history of soap, debunking soap origin myths and breaking down the science of making soap. From sourcing specific wood ash to hunting down ancient recipes, our two experts explore all the factors that are needed to create a good bar of soap.  

Sally Pointer is an archaeologist and freelance heritage educator with a background in museum education and teaching traditional skills. She has recently completed an MSc in Experimental Archaeology at the University of Exeter, where she is now an Honorary Associate Research Fellow. Her research interests are diverse, and she is currently working on projects that explore early textile tools and bast fibres in prehistory. She has an ongoing interest in the development of cosmetics, perfumes and soaps across time and is also working on a book project to explore the history and archaeology of soap. She regularly teaches workshops on ancient skills and traditional crafts and can often be found doing costumed interpretation and audience engagement at heritage sites. She also uses social media and YouTube to help share projects and tutorials on a wide range of topics. The origins of soap have been clouded in myth and misinformation for a long time, and a major project within her MSc and currently being prepared for publication explores the probable scenarios in which true soap was first observed in the ancient world.
