Priestman Blaydon Foundry Coke : advertising booklet issued by The Priestman Collieries Ltd., Newcastle upon Tyne, c1930 : title page
This booklet describes the properties and scientific research applicable to the "Blaydon foundry coke" manufactured by the Priestman Collieries at Blaydon-on-Tyne, a little upstream from Newcastle. Coal is not 'just' coal but different types and seams have differing properties and some, such as for metallurgical foundry coke, are better than others depending on factors such as structure, ash and sulphur content and calorific value.
It shows the details of this specific coke as well as showing some of the laboratory and testing processes that Priestman, obviously a very organised and scientific concern, undertook to ensure the product supplied was consistant. It includes a copy of a letter, dated 1929, from a 'satisfied customer' for Blaydon Burn Coke - this being one Sir W G Armstrong, Whitworth & Co Ltd. They also mention that this specific foundry coke is manufactured in by-product (or bye-products) ovens and that they also produce a coke manufactured for those foundries that preferred the older Beehive Coke, the Priestman Garsfield Beehive Foundry Coke.
