This pot uses three different glazes: Coyote's Green Shino, Spectrum's Textured Hot Chowder, and Duncan's Deep Sea Treasure. Under the Hot Chowder (on the lid and upper area of the pot proper) I laid in vertical streaks of a mixture of copper oxide and copper carbonate.
The results? I love it! I hope you do, too! I also hope that this may inspire you to try out using oxides and carbonates as stains (although commercial stains are cool, too).
