Five fragments of bloomery slag that appear to have been produced from the tapping process. All display smooth molten ridges and channels on the face characteristic of runs of solidified molten taped slag. Where broken the core is seen to be dense but filled with abundant, small bubbles and cavities. These fragments measure 1, 35mm by 33mm 2, 50mm by 35mm 3, 70mm by 50mm 4, 42mm by 30mm 5, 115mm, by 80mm

A large piece of iron tap slag of uncertain date, probably Roman to Post Medieval, about AD 43 - 1600. It is dense, magnetic and black to purple in colour with some rusty patches. It forms a thick plate which is rough and irregular on the lower face and sides, with characteristic runs of solidified molten metal across the top face. Both ends of the piece are broken. In cross-section it is D shaped. Measurements are; length 1694mm, width 1035mm, thickness 453mm. Tap-slag is slag that is 'tapped' from a bloomery furnace. This is carried out during smelting so as to allow the long c…

Two fragments of undated ferrous slag. The fragments are irregularly shaped with a slight patches of vitreous areas. Both frags have some rusty patches, one is much darker than the other perhaps due to increased carbon. Fragment 1: 37.49mm high, 35.39mm wide, 27.46mm thick and 31g in weight Fragment 2: 48.85mm long, 34.45mm wide, 21mm thick and 26.54g in weight. Both frags found in the vicinity of metalworking objects including ingots and crucible.

Four pieces of slag, clinker or other by-product of industry or burning of unknown date (Iron Age to post-medieval, c.800 BC - AD 1800). The pieces have a collective weight of 448g (to the nearest 2g) and three have traces of an orange colour, perhaps from iron. All are formed of bubbles and have a pock-marked surface from burst bubbles. Measurements, in size order: 72.7x66.4x35.2mm; 55.5x47.5x35.4mm; 55.9x43.1x27.9mm; 53.4x42.1x26.8.

Three irregular fragments of iron bloomery waste (slag) or fuel ash, of Iron Age to Late Medieval dating (800 BC to AD 1600). All three fragments are light for their size, which would suggest that minimal iron metal is present within the matrix. All have a honeycomb structure, formed of solidified air bubbles. The measurements are as follows: 1: Length: 24.53 mm. Width: 23.04 mm. Thickness: 15.25 mm. Weight: 3.8 g. 2: Length: 50.57 mm. Width; 31.64 mm. Thickness: 21.75 mm.

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…

Small fragment of iron slag of unknown date. The associated material (being both Roman and also Post Medieval date) suggest that the context of this find is from is either mixed or has a post medieval intrusion; therefore a wide Roman - Post Medieval date is attributed to this find (50-1800 AD). The slag is slightly magnetic and has an orange coloured corrosion product associated. Where it is broken a honeycomb like internal matrix / structure is revealed. The fragment measures 22mm length, is 11.4mm width, 13.2mm thick and weighs 3.41 grams.

A fragment of Iron bloomery slag. The fragment measures 34.03mm long by 29.37m wide and 12.87mm thick. It weighs 16.5 grams. The process of smelting iron ore to produce iron has not changed much from the Iron Age to the Medieval period, so this piece of bloomery slag could date from any time between the Iron Age (800 BC) to the Medieval Period (1500 AD).

Two pieces of iron slag, the larger measuring 187.9g, 61.62mm wide, 66.44mm long and 40.7mm thick. The smaller weighs 175.9g, 65.92mm wide, 68.20mm long and 45.14mm thick. They are both dark both dark brown in color, although covered in light brown dirty. Both are generally sub-circular in plain and section and have a very rough surface. The smaller of the two has some surface areas that are rounded which may indicate that it is part of a bloom or tap, but it is not clearly indicated.
