The Scar plaque is made from whalebone, which was a rare and precious material. However the bones of other, more easily obtained animals were often used by Viking craftspeople to make everyday objects. Antler, animal skins and wool were also used to make clothes and domestic objects. In Viking towns, such as those established at York (Jorvik) and Dublin, archaeological evidences shows that specialist craft workers such as leatherworkers, antler workers and blacksmiths had workshops where they made and sold their wares. Many of these objects were taken abroad to trade as well as being used in the Viking homelands. Below is a selection of Viking objects made of different materials.
