Clay on Brownsea

October  2019
Look at that clay deposit. I grabbed a small handful of each of these layers. I'm curious to find out what the mineral content is to create those colours. Brownsea Island in Poole Harbour used to a have a pottery, I wonderer if it is the same clay they used. 
 Interestingly, it closed down as it wasn't sustainable due to the clay they were using*. However, Poole harbour is home to some of the finest Ball Clay in the world.
