The third glaze cast from the Serpentine rock.

I was so surprised and excited by how the colours and surface texture kept changing. The form also slowly started to move away from the original Serpentine rock due to casting errors, like picking up seams or the material not fully flowing out in to all the details of the mould.

Lustre fired my big rock to create a mirror.

The second big rock cracked during its final high-firing. I filled in the cracks with lustre. 

Began sketching on a third large rock. 

I used red iron oxide and black iron oxide to create more depth and contrast compared to my first two rocks.
