Description:Lantern slide containing a view of the Daisy Bank marl hole, Longton, Stoke-on-Trent, Staffordshire.
These huge holes were created due to the large scale extraction of a type of clay called marl.
This lantern slide appears to be one of a group used for a presentation or slide show by Blake entitled “Staffordshire Pottery.”
A small folder containing approximately sixty reader cards was found in the same box as the slides. The cards contain information about the images. The card that appears to correspond to this slide reads;
"A Marl Hole. Coarse clays are obtained locally from such pits as this. Kaolin or china clay is brought from Cornwall."
