MULLER

Unique ID: CORN-401EC1

Object type certainty: Certain
Workflow status: Awaiting validation Find awaiting validation

A fine-grained granite or aplite muller or rubbing stone dating from the Bronze Age. The muller is oval in plan and plano-convex in profile and section; 216 mm in length, 134 mm in width, 80 mm in thickness and approximately 2.9 kg in weight. The shape of the muller suggests that it was made from a beach cobble, one face of which has been ground to produce a smooth flat surface. The convex surface is scarred by two shallow, parallel scratches where it has been hit by an agricultural machine. The flattened surface displays evidence of use as a rubbing stone: the two ends are very slightly convex and the central area is slightly concave. There are fine striations across the width of the muller, mainly towards the centre, possibly the result of friction during the grinding process when it was used to crush grain into flour with a saddle quern as a base. The aplite contains quartz, pale felspars and dark tourmaline, with the former mineral wearing down and the latter being harder so an undulating surface is formed that is ideal for grinding grain (Roger Taylor pers comm). The beach cobble most likely came from an aplite dyke formed within the Land's End granite outcrop.

Jones & Taylor (2010) illustrate a porphyritic elvan muller with small quartz and feldspar megacrysts, which has been derived from a beach cobble, excavated from Scarcewater, St Stephen, on page 127, fig.64, no.253, which is dated from the Middle Bronze Age, c.1500-1100 BC.

Jones (2002) illustrates a similar broken fine-grained granite elvan muller from Callestick on page 32, fig.13, no.95 which dates from the Later Bronze Age, c.1100-700BC.

Nowakowski (1991) illustrates a similar elvan example excavated from Trethellan on page 142, fig.57, no.88, which dates from the Middle Bronze Age, c.1500-1200 BC.

CORN-2E639A records a very similar fine-grained granite muller, also from St Hilary.
