●
The nineteenth-century 'Wheeler Brothers' rubber, though quite firm,
produced an excellent arris.
●
The eighteenth-century Berkshire rubber, apart from a less clean body
(from as-raised clay), performed exactly as a twentieth-century TLB Orange
Red made from the same, but washed, material.
●
The two types of TLB rubbing bricks, the Orange and the Cherry Red
clearly revealed why the latter was the superior rubber. Both were open-
textured but the Cherry Red was less sandy and had a noticeably finer dust;
both cut and rubbed very easily.
●
It was interesting to note how the rubber used for the ashlared gauged
work and niche body at Eltham Orangery (see case study, p. 182) was much
firmer than the rubbers selected for the carved 'scallop-shell' niche boss.
All the modern rubbers, except the Hampshire rubber, proved much harder,
although they still cut and rubbed well, with good arrisses:
●
The Sussex rubber was quite dense and, although it had few air pockets,
was speckled with tiny flint nodules and was quite hard to cut.
