45D 330 80 72209

Found by Ian Suddaby at the old Manuel Works, Whitecross.

This example is not in my possession.

  • Stein, Castlecary Fireclay Works, Castlecary, Stirlingshire.
  • Stein, Manuel Firebrick and Refractory Works, Whitecross, Stirlingshire.
  • Stein & Co, Anchor Brickworks, Denny, Stirlingshire.
  • Milnquarter Fireclay & Gannister Works, Bonnybridge, Stirlingshire.

Ian states – Tongue and Groove brick with a hole cut through it. The blue markings are hard to read but it’s 45D which is the Alumina content and Dense. The rest is probably the size, it certainly says 330 at the top which is the length and 80 at the bottom which is the thickness. There is a number on the end too.

It is entirely possible that the core was taken out and used for laboratory analysis.
