John Gilchrist Stein – Fire brick core samples

The following fire brick core samples were rescued by the late Joan Faithfull in 2001 when the Manuel Firebrick and Refractory Works, Whitecross closed down. They were generously donated to my collection by Joan’s husband, Monty Faithfull and her son, John Faithfull.

Such core samples would be sent to the Stein laboratories for tests and analysis. The ones below were simply kept for reference purposes.
