AndreaB Posted August 25, 2020 Report Share Posted August 25, 2020 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 Link to comment Share on other sites More sharing options...
liambesaw Posted August 25, 2020 Report Share Posted August 25, 2020 Alumina oxide or alumina hydrate depending on the form, both get the job done. Link to comment Share on other sites More sharing options...
