Found by Ian Suddaby in the Ravenscraig, Motherwell area.

This example is not in my possession.

Unidentified manufacturer.

Find location would suggest Scottish origins but …

Ian states – Dalzell/Colville at Motherwell again and a badly traumatised brick. I had to highlight the letters here as the cracking has misaligned them and they’re hard to see. With a brand name like DOLO this must be a Dolomite brick, the first one I’ve (knowingly) found. There is lots of Dolomite in Britain but the manufacturing process is complicated and I’m not going into detail. However, it’s important to stabilise the CaO part as it reacts with water and it’s combined with silica to achieve that before firing. I don’t know who made this brick but I’d guess at either General Refractories or Steetley in Worksop, Nottinghamshire.
