Early kaolin-based ceramic fibres in the US.
Ceramic fibre · Spun refractory fibres for 1000–1400 °C — kiln linings, gaskets, and a respirable-fibre caution that AES grades try to ease.
Ceramic fibre did not arrive as a finished commodity. 1940s–60s US/JP; EU RCF classification 1990s around United States / Japan / EU 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.
Early kaolin-based ceramic fibres in the US.
Furnace lining without firebrick thickness.
Anchored folded blankets for petrochemical heaters.
RCF classified; workplace rules tightened.
Alkaline-earth silicate wools, lower biopersistence claims.
Exposure limits as the product differentiator.
Still higher T, different process.
Structural steel and ducts — check which fibre.
Many EU sites specify AES unless T demands RCF.
Still immature versus mineral wool.

Knowing this timeline is how to read a mill certificate without treating Ceramic fibre as timeless.
CaSO4·2H2O panels that buy fire time by calcining — the everyday A2/A1 lining of interiors.
