AndreaB 54 Posted August 25 Report Share Posted August 25 Hi everyone, Quick question: we use calcite alumina, or alumina calcined (in South Africa) under ware when glaze firing to provide a surface allowing movement to avoid cracking, what name does the rest of the world use? TIA Andrea Quote Link to post Share on other sites
liambesaw 2,615 Posted August 25 Report Share Posted August 25 Alumina oxide or alumina hydrate depending on the form, both get the job done. Quote Link to post Share on other sites
