Nernst glower / spark
Early oxide electronics and ignition ceramics.
Technische Keramik did not arrive as a finished commodity. 20th c. spark plugs / WWII carbides around Germany / US / Japan still explains who makes it and which tests it sits in.
Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.
