Carole's Pottery: Iron Lustre under stripes of Ancient Jasper, Iron Lustre, Chun Plum, and Oatmeal each.
I use water to help the glaze sit down in the imprint. If your glaze is too thick it will trap air bubbles in your imprint and no one wants that. There is no specific amount of water or amount of time you wait before wiping the tops clean. The main thing I would recommend is practice, patience and experimentation
