Ceramic Jiggering Process

Slipcasting is one technique for mass production and ideally suits shapes that can not be made by other methods.

Ceramic jiggering process.

This process opposite to that of the jiggering. Other ceramic processes include pressing squeezing powder into a mold casting and jiggering laying raw material into a rotating mold. Jiggering jiggering is a process of forming pottery that employs a spinning plaster mold and a tapered template to press soft clay or porcelain against it. A mixture of fine grain zircon zrsio 4 aluminum oxide fused silica bonding agents and water creates a ceramic slurry.

A liquid clay body slip is poured into plaster moulds the permeability of the mould drawing water from the slip to leave a layer the clay body of the internal shape of the mould. A template is half the profile of the piece being made and is cut out in a strong thin material like plastic wood or metal. Using jiggering we can finish the inner side of the product. The mold shaping the inside or outside is on a wheel and covered by a flat piece of clay.

Advanced engineering ceramics are often made in more advanced ways. Jiggering is a method to form the outside of a plate and jollying the inside. Amazing ceramic making projects with machines and workers at high level in this video. A shaped roller or template then presses the plasticized mix against the wheel to forge the shape.

Jiggering is a method to form the outside of a plate or bowl and jollying is forming the inside. A method to form outside of the product. Ceramic cup saucer production process. There is a fixed unmovable arm that holds a template.

A de aired mix is placed on a shaped rotating wheel. While a great deal of modern pottery is molded some is still thrown by hand on a foot powered wheel in the traditional way. The process the first step in manufacture by ceramic mold casting is to combine the material for the mold. Jiggering involves the mixing of a plastic mass and turning it on a wheel beneath a template to a specified size and shape.

This slurry is poured over the casting pattern and let set. Processing addition to these standard processes jiggering is employed in the manufacture of tableware. It is similar to making something on a wheel but turned into an industrial process.
