Report for H M Coroner

Treasure Number: 2017 T393

Find Spot: To be known as: 'near Manningtree'

PAS Database number: SF-360E9A

Period: Bronze Age

Finder: Dave Haffenden

Date of Discovery: March 2017

Circumstances of discovery: Metal detecting on ploughed land with the landowner's permission

Description: A hoard of three Bronze Age copper alloy objects, including a complete socketed axe, a fragment of a socketed axe and a metalworking debris consisting of a casting sprue.

The complete axe is in good condition. The blade end curves outwards gently with flared sides. The sides of the axe curve inwards slightly and then out again towards the socket. The socket is square in cross-section, has a thick raised ridge around its rim and an additional raised collar 5.5mm behind this. There is a casting seam running along the centre of each side. An integral, low, semi-circular loop, oval in cross-section, extends from one side behind the socket rim, the casting seam also running through it centrally. The metal is bright green in colour with a little pitting and corrosion in places, but is otherwise in generally good condition. There is some damage around the socket and recent scratch mark on one face at the blade end.

The fragment consists only of the blade end of a socketed axe. The blade curves outwards gently and has slightly flared sides. In the centre of the rear end is a roughly rectangular recess - the remains of the much longer socket, which has been squashed together in one place. A dark green, shiny surface patina survives in places, but there is heavy corrosion around the edges and the breaks are well worn.

The casting sprue is roughly cylindrical in shape with two jets extending from its narrower lower end. Each jet is roughly cylindrical and terminates in a flattened expanded end. Sprues like these are the by-products of the casting process, created at the mouths of moulds where the metal is poured in. The presence of the two jets suggests that metal was being poured into two moulds simultaneously.

Dimensions:

Socketed axe - length: 102.0mm, width of blade52.87mm, thickness of blade: 3.18mm, width of socket: 42.71mm x 43.01mm, thickness of socket: 6.12mm, length of side loop: 21.51mm, width of loop: 11.96mm, thickness of loop: 5.59mm, weight: 264.6g

Socketed axe fragment: Length: 46.20mm, width: 32.84mm, thickness at socket side: 12.65mm, thickness at blade side: 5.23mm, weight: 49.26g

Casting sprue: Length of outer section: 37.38mm, width of outer section: 33.05mm, length from top to bottom incl. two inner jets: 26.83mm, weight: 64.11g

Discussion: The socketed form of the axes suggests a late Bronze Age date for the group, c.1150-800 BC. The metalworking debris was found together with these and seems likely to have been associated in some way.

The group includes more than two base metal objects of prehistoric date. Consequently it qualifies as Treasure under the stipulations of the Treasure Act 1996.
