Description

The standing furnaces are built of stone and brick, on a square plan. Their ashlar stone elevations taper towards the top, although each survives to just below original height. The side elevations contain small, intact tuyere arches.

Furnace No 2 - This has a number of tie bars in the upper part of its front and side elevations. The furnace retains its original stone casing and cast house (listed separately).

Furnace No 4 - This has a large hearth opening or tymp; formed as an outer semi-circular brick-lined arch and an inner segmental brick lined arch. Above the level of the top of arch, all facing stone of the outer furnace shell has been removed, exposing stone core and the conical refractory brick lining.

Furnace No 5 - The same form as Furnace No 4. Hearth opening arch survives less well.
