There are four ways that copper-alloy vessels were made: by casting, raising, dishing or riveting. [ARWIDSSON 1984] Petersen argues that many of the copper-alloy vessels from Norway were insular because they contained a large percentage of tin, an alloy not found in Norwegian copper-alloy [PETERSEN 1940:p.8].<br>
...... The subject is discussed by Speed, Greg & Walton Rogers in their paprer on the Adwick-le-Street grave [SPEED, GREG & WALTON ROGERS 2004:p.80]. Here they site two more differing views; David Wilson writing in 1973 thinks that the Scandinavian metal workers would have been capable of producing Copper-alloy vessels; and Gustaf Trotzig writing in 1991 regarding metal vessels from Gotland agrees with Petersen's opinion that these were imports.
