Plaster of Paris Bandage consists of a leno wave bleached cotton gauze impregnated evenly with Calcium Sulphate which has been dehydrated so that it consists substantially of the hemihydrates, to which adhesives and setting-time modifiers may have been added. It is reasonably free from loose power. Bandage lees than 5 meters long have no joins; joins in longer bandages are made using a suitable adhesive and not by sewing.
