[2] During the 10th century, farming was the main activity, with the local reddish-brown clay being used to create suitable building bricks, topped with slate roofs.

[3][4] But it was not until 1720 that local potter John Astbury of Shelton discovered that adding heated and ground flint powder to the local reddish clay could create a more palatable white or cream ware, that sold at higher volumes to the natural Staffordshire Potteries reddish colour.

The flint was sourced from either the South Coast of England or France, and then shipped to the Port of Liverpool or Shardlow, near Derby on the River Trent.

[3] After shipping to the mills on pack horse, it was sorted to remove the flint with reddish-hues, and then heated to 1,200 °C (2,190 °F) to create an easily ground product.

[3] However, the grinding process produced a fine siliceous dust, that after adhering to the workers lungs resulted in cases of silicosis, similar to the condition of pneumoconiosis suffered by coal miners.
