Slip casting is a forming technique, not a powder preparation technique.

Sintering is a heat treatment process that causes the ceramic particles to bond together, resulting in a denser and stronger material.

Hot pressing is a sintering technique, not a forming technique.

Glazing is a process of applying a thin layer of glass to the surface of a ceramic, which creates a decorative finish and protects the ceramic from wear and tear.

Earthenware glaze is not a type of ceramic glaze, it is a type of ceramic body.

Clay is the main ingredient in a ceramic powder, as it provides the plasticity and binding properties necessary for forming.

Machining is not a ceramic forming technique, it is a subtractive manufacturing process used to shape materials by removing material.

Ball milling is a process of grinding ceramic powder in a ball mill to reduce the particle size and increase the surface area.

Spark plasma sintering is not a common type of ceramic sintering technique, it is a relatively new and specialized technique.
