Ceramics I Sgraffito Carving the Pinch Cups сграффито

This is for my Ceramics I students, showing the process and tools to create their sgraffito carving on their earthenware pinch cups. The design is entirely up to my students, I just show my geometric type designs I love to do! The clay is Standard 103 Grogless Earthenware, and the underglaze is Amaco Velvet Jet or Velour black. (I forget) I apologize for the periodic focus problem... I am filming these by myself after long days of teaching, and am limited by my equipment!
