As the old chemical works in Leith are demolished a long deceased body encrusted in phosphate rock is discovered. Seated at a card table he has ten objects laid out in front of him. Whose body is it? How did he die and what is the significance of the objects? A mix of science and anecdote, layered and interconnected stories present the chemical factory as a complex, beautiful, dangerous and integrated whole, exploring how a workforce operate technology they do not understand, the common occupational accidents of the 1980s, the skill of ‘unskilled’ work, and what happens to those left-behind as manufacturing work disappears east.
