Hi ackee, to answer your question above I find the pictures that I put links to because I spend too much time looking for clay online lol! I like to do different searches to see what I can find, and then drool over the pictures.Type in Images of Kaolin mines and you get to see some beautiful pictures. My favorite is the two men standing in the middle of a crater. They are surrounded by clay.
I've done the kaolin mines search. Thanks; some great, delicious looking images.
