Best used when making very large series of spin blown glass shapes, where extra high demands are made on the surface finish.
Ceramic material shares many of the characteristics of graphite in being resistant and durable, but has a different density. This difference gives blown items an extra shiny, high quality surface. But it is also slightly more expensive material than graphite.
Unlike graphite, ceramic material does not require any coating, but has to be cleaned in an ultrasound bath after every 1000 pieces you have blown. Therefore, this type of material is more often used in very big glassworks rather than in small hot glass studios.
