All my examples are as close to the originals as I can make them. they are red earthenware covered with a white slip. I then carve designs in them, the designs are pretty thick so they are considered "champleve" rather than scraffito. After they have been bisque fired I glaze them with a lead-free transparent glaze (I guess that isn't exactly like the original) and loosely glaze them with green and yellow glazes. The green and yellow are also lead-free. The glazing is very loose and doesn't try to be precise, and that is like the originals.
