I did a series of three small 14-inch torsos: Luna, Mars and Torso Abstraction. Mars has a dark purple-brown slip from my creek silt that has been rubbed lightly off with an iron oxide wash. I attribute this directly to the study of traditional American potters techniques. This full-round male torso with head has emphasized musculature that gives him a powerful presence.
I applied the heavy slip to green ware. The rough outside texture I prefer swallows the dark slip in every crevice. Wiping it off in the green ware state gives a softer surface, much more pleasant to touch with all the detail in tact.
