[Canterbury Museum ID] 2007.160.63 [Title] Fire brick, angled mark [Notes] Probably double baked to get depth of colour. Clay colour and type suggest West Coast maker. Firebricks were more likely to have brand marks than frogs as it was important to have a recognizable brand as a guide to the special qualities of the bricks.

Part of a dull deep red fire brick with no frog but four deeply pressed angled marks. Probably came from West Coast from the colour and look and is dated between 1853 and 1872.
