from Pierowall, Westray, Orkney
This brass oval brooch was found in a burial from the Viking age cemetery at Pierowall on Westray in Orkney. It dates from the 9th century. This picture shows the back of the brooch.
The oval brooch was cast in a single piece using the lost wax method, as indicated by the textile impressions. In a complicated process, a master cast was made from which a number of moulds were formed by pouring molten wax into the mould.
Textiles were used to reinforce the wax master cast in the production of the brooches. When the mould was heated and the wax melted away, the textile impressions remained on the metal.
