Jim has asked for more information about his pictures of Boulby Alum Works. These works operated from about 1670 until 1870 to produce alum crystals from the abundant shale.
Boulby Alum Works flywheel.
About 6 feet diameter and found on the floor inside one of the rooms in the workshop range. Being cast-iron and extremely heavy it was reburied onsite. A year or two later it was searched for but not found, the conclusion being that someone had found it and bowled it over the cliff edge. Pieces not even found on foreshore below.
The use of the flywheel is unknown but possibly may have been part of a hand-operated pump and usually operated by women.

This workshop was the end room in a range with a forge at both ends of the room. This is a view of the western forge; next to the pot is a store for tools then the remains of the fire itself.

Looking east along workshops range from western forge. Mrs McP is beside eastern forge standing on site of bellows, and next to fire. Note tool store and site of quench pot. First room beyond had been wood-lined with broken thin glass on floor. Probably used to assess specific gravity of alum liquor.
Next room was a coal store and furthest room was an office with fireplace.

May have been a NMRS visit. Could be Roger Pickles in the green shirt.
B.A.W. General view.
In the foreground is the workshops range and between there and the cliff edge was the range of steeping pits for soaking the calcined shale. My father Keith Chapman (to right wearing light blue) is standing with the group at the flywheel. In right background is myself (the good-looking one) with my brother Nigel wearing the white shirt.
B.A.W. General view.
Looking down on the site with workshops at left edge. The cliff edge features were where the liquor supply from the steeping pits was conveyed into 3 circular tanks for concentrating before being passed along a wooden trough about a mile to the boiling house.
Any questions?
Yes, I'll have it - what is it?
