The conference itself was attended by a wide range of archaeologists historians scientists conservators and crafts people and this is reflected in the subject matter of the articles. The topics discussed include the use of colourants by indigenous peoples in different parts of the world on a variety of substrates; the wide range of materials identified on a group of middle-class Japanese kimonos; precious religious textiles from Romania and recipes used by a late-eighteenth-century Antwerp dyeing company. This gives a flavour of the wide-ranging theme of this Reprint.</span></p>
