Formation technique with jigger-Jolley is one alternative in the formation of ceramic objects, this technique is a combination of rotary techniques with printing techniques and engineering lathe. The formation of the jigger-Jolley techniques can be produced ceramic objects with the same shape and size, but not all forms of ceramic objects can be created with this technique.
Formation with a jigger-Jolley is in principle using the mold (mold) of cast material (plaster of paris), which can be removed and spun in the mold holder (cup wheel head) and is formed by forming a knife (profile).

Generally good tool jigger-Jolley and masinal masinal used to create or rnemproduksi ceramic objects in jumIah many (mass production). with the same shape and a relatively fast, but the type of ceramic objects that can be produced with this technique is limited to shapes such as cups, bowls, bowls, and plates.
The process of forming a ceramic object-Jolley jigger machine can be divided into 2, namely:
Jigger
Formation kerarnik objects with typically uses a rotating plaster mold to form the inner and blade forming (profile) is mounted on the rod handle (tool holder) to form the outside of the ceramic objects. Usually used to make ceramic objects shaped bowls and plates.
JolIey
Formation of ceramic objects using a rotating plaster mold to form the exterior and knife-forming (profile) which is mounted on the rod handle (tool holder) to form the inside of the ceramic objects. Usually used to form ceramic objects such as cups and bowls.
The process of formation of ceramic objects with jigger-Jolley also requires a lengthy process if the existing equipment is not equipped with a plaster mold and blade forming (profile), because the mold must be made in advance before forming his ceramic objects.
