Attaching wet parts

Attaching wet parts: The first thing you learn in ceramics is "score and slip." To attach 2 wet pieces of clay, you score both sides with a needle tool or fork, apply water or slip, and mush them together. However, some potters, even famous ones, have abandoned the traditional score and slip method, saying they found direct contact to be more reliable. When using the direct contact method, it helps to have a binder. Vinegar works great for this, almost like a glue.
