Score

To make scratches or creases in pieces of clay to be joined together. Scoring and applying slip to such roughened surfaces creates a bond that holds the pieces together. If slip acts as an adhesive, and scoring makes two pieces of clay like the opposite sides of a zipper, their combined action — a zipped zipper with hardened adhesive inside — should be permanent. See coil and slab construction. (artlex.com)
