Lead lettering on a gravestone. Note the evidence of a 'streaking' pattern on the surface. This could be the reuslt of an overhanging tree dripping onto the top of the gravestone. The discolouration is probably an algae growth following the path of the dripflow.

Lead lettering was here. Removal of lead lettering can sometimes restrict the areas of the gravestones upon which weathering cna be measured. Note the relatively roughened nature of the surface. This surface would have a 'sugary' texture if touched. The presence of distinct microenvironments can also be seen on this gravesotne. The craving produces areas of shelter and these have become blackened by deposition.

Lead lettering curling at edges. Once again progressive removal of the lead lettering limits the area of the surface that can be measured. As the letter curls or peels away from the surface it beceomes increasingly loose and detached. Measurement of such a letter woudl produce erroneously high valeus for loss.The peg holes into which the lead lettering is originally inserted can be clearly seen.

The height difference that can be measured using calipers is visible in this image. The lettering is not peeling away from the surface and so is likely ot represent the original surface of the gravestone.
