A number of years ago, when Sabine and I ran the very first European Textile Forum, one of the papers was about the dyeing industry at Pompeii. Heather, who gave that paper, got together with Sabine the very next day, and some dyeing took place, and the paper and the dyeing and the ensuing discussions resulted not only in a friendship but also in a number of follow-up archaeological experiments looking into the influence of metal kettle materials on the dyeing outcomes.
The basis for the presentation that Heather gave back then was her PhD thesis about the dyeing industry in Pompeii - and I'm very delighted to say that it has now, finally, been published by Archaeopress. It's called "Investigations into the Dyeing Industry in Pompeii. Experimental Archaeology and Computer Simulation Techniques" and you can get it as an e-publication or the printed version, either directly from the publisher or from the bookseller of your choice.
