To Duke Julius the effectiveness of his cannon balls made of slag was well known. This slag of the cannon balls contained ca. 10% of heavy spar, 15 % of zinc and 10% sulphur. These ingredients avoided the natural healing process of wounds. The balls have been made with Diameters of 180, 94 and 74 mm and sold in great amounts to interested buyers.
Some years ago such balls in an amount of more than 1000 have been found during digging works.
