An assemblege of eight pieces of slag. Seven of these pieces are undiagnostic slag (metal working waste). See Historic England: Archaeometallurgy, Guidelines for Best Practice 2015, p.23. Pieces A, F & G (see image) have a strong magnetic reaction and will jump off of a table top to attach to a strong magnet held near-by. Pieces C & E have a weaker magnetic reaction, moving slightly if a strong magnet is held near-by but not moving to attach themselves to the magnet. All of the above have a mid to dark grey colour, dull and roughened texture. Pieces B & D (see image) …

Fragment of silver with one curved edge and the other edges rough, flat on both sides. Its shaped suggests that it is a bloom from a crucible. L.: 37.4mm W.: 28.4mm Thickness: 6.9mm Wt.: 27.05g Date: probably ancient, possibly Roman. The weight corresponds to almost exactly a Roman uncia, i.e. one-twelfth of a Roman pound (327.45g), and it must be considered a possibility that this is not coincidental. Note: Roman coins and pottery have been found in the same field. Note: this item is made substantially of silver and is more than 300 years old, and thus qualifies as treasure…

Ten fragments of iron tap-slag of varying size and shape. These fragments have a total weight of 812.83g. All of the fragments have areas that give a slight magnetic pull but also have areas which do not react to a magnet. Photographs of the fragments were shown to Mr Peter Boardman who confirmed the tap-slag identification and commented that some of the fragments show nice run patterns on the surface. He went on to comment "it looks like it is" possibly "post blast furnace invention/development so could date anywhere between the 1300's onwards" to very modern "but am unable to confir…
