Tin blowing mill, Teignhead Farm

Historic England's scheduling record (list entry 1019217) describes a tin blowing mill at the foot of a steep scarp 3 metres high beside the North Teign. The building is of drystone with walls up to 0.8 metres high and measures 13.6 metres by up to 3.5 metres inside. In the mill two edge-set stones mark the furnace where black tin (cassiterite) was smelted. A hollow beside the north wall is the wheelpit, where a water wheel worked the bellows. The molten tin was ladled into a big mould stone with two troughs standing by the furnace, and a second, broken mould stone lies in the entrance. A rectangular structure 5.5 metres by 2.3 metres is attached to the south-east end of the mill, with a rubble wall up to 1.2 metres high. It lies in the parish of Dartmoor Forest, about 1.3 km north of Sittaford Tor.

South of the mill is a series of earthworks, some left by earlier streamworking and others possibly from dressing and washing the ore. Beyond them, beside the river, is a 19th-century drystone wall with a broken mould stone and a mortar stone built into its top, and these are included in the scheduling.
