Lead masonry cramp sheathing. Cast object, probably intended to receive ironwork inserted into stone, where the lead would retard corrosion of the iron and the consequent splitting of the stone. This example appears to be an unused and flawed casting made in an open mould. The slots next to the rectangular rebate may be intended to ease removal of a warm casting from the mould by inserting a small tool. Lightly patinated overall. Suggested date: Post-Medieval, 1850-1900. Length: 30.2mm, Width: 18.7mm, Height: 15.6mm, Weight: 32.37gms.

Lead bedding for a masonry cramp. The object is cast, of tapered rectangular form with a round hole at one end and a larger tapered rectangular aperture at the other, the latter uppermost when the molten lead was poured. Described as the foot of a vessel by the finder, this object could perhaps be part of a garden ornament of relatively recent date. Alternatively it may be part of the lead sheathing for an iron masonry cramp, in which case it would have been poured into a rectangular rebate in a large stone, to receive an iron pin. The lead would retard the corrosion of the iron cramp…

Lead architectural fragment. A fragment of lead from the setting of ironwork in masonry, as with a railing or a masonry cramp. The molten lead was poured so as to retard the corrosion of the iron and its consequent expansion, which might otherwise split the stone or brickwork into which it was set. The embedded object [lost] had a width or diameter of c.18mm. Patinated. Suggested date: Post-Medieval, 1600-1900. Height: 35.5mm, Width: 26.2mm, Thickness (maximum, at 'wall' of object): c.7mm, Weight: 50.67gms

Lead architectural fragment. A fragment of lead thought to have been poured to secure a masonry cramp or other ferrous metal fitting in stonework. One side bears a smooth rounded hollow, an impression of the rounded object against which the lead had set - possibly a railing. Lightly patinated. In the suggested usage, the lead would seal a metal insertion to retard its corrosion and the consequent risk of splitting its setting. Miniscule traces of rust appear on the inner surface. The upper surface which would have been accessible once the lead had set bears multiple marks from a trian…

Lead architectural fragment. A massy cast sub-rectangular block of lead with the imprints left on two adjacent sides by flat-sided objects: the more complete was of trapezoid section measuring 16mm by 20mm, while one of the others oriented in the same direction was 23.5mm wide. The lead was probably poured to fix the ends of railings or other ferrous metalwork set into masonry, and to retard their corrosion which might otherwise split this setting.

Lead sheathing for iron inserted into stone, as with a fencepost. Cast fragment with fluted or ribbed outer surface, an upper flange where surplus lead has solidified, and a smooth surface within which retains flakes of rust. Patinated overall and rolled up at one end. The juxtaposition with corroded iron may suggest this served as a sheath for structural ironwork to prevent its corrosion and expansion from shattering a stone setting. In such usage, the lead would be poured to fill the space between the iron and the sides of the rebate into which it was inserted. The fluting presumabl…

Lead possible architectural fragment. A thick cast oval-section finger-shaped object with a rounded lower end [as cast], and with a deep moulded straight-sided longitudinal hollow of length 35mm, width 14.5mm and thickness 6.6mm, possibly formed by the pouring of lead around an object embedded in brick or stone. Lightly patinated. For an iron object, such as a masonry cramp or the end of a railing, this sheath might be intended to retard its corrosion and so protect its setting from cracking through the expansion of the iron as it corroded. In this case, there is no sign of rust, so, …

Lead possible masonry cramp. Cast sub-annular object of plano-convex profile with a tapering moulded aperture of diameter c.18-13mm diameter. Patinated overall. The flat side shows signs of the pouring and cooling of metal in two stages. This object may represent the pouring of lead around a masonry cramp, a technique to prevent ferrous metal rusting and exploding the material - usually stone - which it was intended to secure. Suggested date: Post-Medieval, 1500-1800. Diameter: 39mm, Thickness: 16mm, Weight: 86.33gms.

Lead possible architectural fragment. An oval sleeve of cast lead with a flange on its upper side [as cast] which appears to have been used to sheath another object, probably being poured when the latter was set in its position. This may have helped secure light ironwork such as a railing or hinge pivot set in masonry, and would retard its corrosion. If so, the arrangement was disrupted before the iron rusted. A grey tint to the metal indicates a relatively recent date. Suggested date: Post-Medieval, 1800-1900. Length: 33.2mm, Width: 17.3mm, Height: 10.2mm, Thickness: 2.1mm, Weight…

Architectural fragment. Probably Magnesium Limestone, as occurs near Tadcaster, Doncaster and Roche Abbey, South Yorkshire [non-specialist identification by MF]. In the Humber region, this stone was used – as at Beverley Minster – from the 1220s onwards. A moulded segment, probably from the side or jamb of a doorway from a stone building; a lack of rebates to hold glazing rules out use in a window. The block is of triangular section, with symmetrical moulding of its inner and outer sides [as set in the building wall]. At the apex of the triangle – closest to the putative opening…

Lead architectural fitting. A conical object of lead with a crisply defined central aperture of 9mm square and a flange around its upper side. This is probably from the base of an iron railing embedded in stone. The lead would have been poured around the inserted member so as to help secure it, and in the longer term to retard its corrosion, which, unchecked, would result in the expansion of the iron and the consequent splitting of the stone. The metal retains a grey tint, pointing to a recent date. An iron bar 9mm square would also appear to have respected the metric system, introduc…

Lead architectural fragment. One half of a poured and cast lead plug with a rounded base and flat top, and with one side of a rectangular rebate of width 11.7mm passing through its centre. Patinated. This was presumably poured into a rebate in stone or brickwork where an iron fixture was set. This would seal the ferrous metal to retard its decay and, as it eventually corroded, would prevent it splitting the material in which it was set. The lack of rust staining may suggest the setting was disrupted before it corroded. Suggested date: Post-Medieval, 1700-1900 Height: 27.2mm, Width:…

An irregular chunk of a dense off-white stone in which crystalline structures appear to run in two distinct planes. These are exposed at either sub-oval end as a mass of  platelets set on end, with zones of a contrasting orientation on its sides exhibiting a smoother or finer-grained surface with linear striations, though still sparkling under strong lighting. It is uncertain whether this material may originate from veins in the local chalk geology, or from an imported building stone. The texture of the material appears, however, too friable for any sculptural use. It wa…

Pale grey flint with cortex, cobble. A fragment of a nodule trimmed to rectangular form by hard hammer strike. This would be apt to use in building or road-mending, which were possibly agencies contributing to the importation of the wealth of patinated flint reported from the vicinity. The struck surfaces are misted but not as highly patinated as much of that material.

Lead possible architectural fragment. A small cast plano-convex object with a central round moulded aperture of diameter 8.3mm, and with its edges on the convex lower side [as poured] apparently formed by the cooling of successive dribbles of molten lead. This resembles poured lead used to anchor and retard corrosion of iron used either as masonry cramps or railings, though here at a rather small scale. This usage is best recorded for the post-medieval period. Alternatively, perhaps a hideously abortive homemade whorl. Suggested date: Post-Medieval, 1500-1700 Height: 14.6mm, Length: 3…
