So you can not feel the lines ?? "Incised" would be scratched into the clay so you could not feel the lines !! Sorry to be so technical but need to know !! I have been looking for a raised mark,, not an incised mark !! A Raised mark would indicate a molded piece with the mark as part of the mold,,incised or scratched into the clay could be a hand made or studio piece as well as just hand decorated !! The mark would have to be scratched into the clay as the plate was being made !!
