What are the 2 steps for antiquing a ceramic surface

Glazing and color washing, apply pigment into the ridges and recesses of the piece. Dry brushing highlights raised areas of the object. You can also use dry brushing to give you the control to add small amounts of color to specific areas, whereas glazing and color washing apply pigment to larger surface areas. Any of these decorative processes will give your ceramic figurine or vessel a distressed appearance, making it look older than it really is.
