Below is a picture of some real horse hair I fired a couple of years ago, followed by my try at some "fake" horse hair. The fake stuff hasn't been fired yet, so we'll wait and see what the finished result looks like. I carved the line into the pot with a small loop tool and filled it with a black slip, scraping off excess slip after the pot dried a bit. Then I stained above the line with a black stain, and burnished the pot, adding some terra sigilatta when the pot dried.
A day for planning
