Ceramic molding is a versatile and precise manufacturing process that transforms clay or porcelain into intricate shapes. Employing techniques like slip casting or press molding, artisans create precise replicas of original models. After molding, the ceramics are fired at high temperatures, ensuring durability and aesthetic appeal.
Ceramic mold casting, also known ambiguously as ceramic molding, [1] is a group of metal casting processes that use ceramics as the mold material. It is a combination of plaster mold casting and investment casting. [2] [3] There are two types of ceramic mold casting: the Shaw process and the Unicast process. [4]
Ceramics of Indigenous peoples of the Americas is an art form with at least a 7500-year history in the Americas. [1] Pottery is fired ceramics with clay as a component.

A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. [2] The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object.
A RAM press (or ram press) is a machine, invented in the USA in the mid-1940s, that is used to press clay into moulded shapes, such as plates and bowls. In operation a slice of de-aired clay body is placed in between two shaped porous moulds, and vertical movement of the moulds presses the body into the required shape.
If technical ceramic parts are needed where the length to diameter ratio is very large, extrusion may be used. There are two types of ceramic extruders one being piston type with hydraulic force pushing a ram that in turn is pushing the ceramic through the loaded material cylinder to and through the die which forms the extrudate.
The casting slip is poured into a porous mould. Due to capillary pressure from the mold, a semi-solid particulate layer is formed on the mould through deposition of the solids in the slip. After a period of time, determined in advance by testing, the cast piece is removed from the mold; the cast needs to be sufficiently firm to handle without ...
There are two main classifications of stirrup spout vessels in Moche ceramics. One form was the process of creating a three-dimensional mold and using this to form the clay into an intricate image or figure. One of the most popular Moche ceramic styles was the creation of what is now called Moche portrait vessels. These vessels were extremely ...
