Groggy clay

Groggy clay refers to a type of clay body that contains a high percentage of grog, which is a gritty, coarse material made from crushed and ground fired pottery or other ceramic materials. The addition of grog to clay serves several purposes:

Reduces shrinkage: Grogged clay has larger particles, which helps reduce drying and firing shrinkage, making it less prone to cracking.
Increases strength: The grittiness of grog gives the clay body added strength, making it easier to work with, especially for hand-building and sculpting.
Adds texture: Groggy clay can produce a unique, rustic texture, often referred to as “tooth,” which can be desirable in certain ceramic pieces.

My head arrived today and is possibly my favorite Bill Fisher piece so far
