Picture to come.
A reddish metal used for vessels and, alloyed with tin or zinc, for bronze and brass objects. England had no working copper mines in this period: medieval copper was imported from the Continent, mainly Germany. It went to brasiers, who cast cauldrons, pots and other items, and to metalworkers. English copper mining resumed only in Tudor times.
