The glass seen here comes from Joseph Crosfield & Sons Limited at Warrington. Okay it's not the most exciting piece of glass in the world but it's unusual to have a positive attribution for a plain unmarked piece like this. The photos come from a distant descendant branch of the Webb family in Warrington. This was bought as "Crosfield glass", probably between 1900 and 1940.
From what I can gather, Crosfields took over the Bank Quay glassworks in 1893. They were involved in various enterprises, mainly soap making, so glass might have just been a sideline or a sub-business.
There are a few Warrington residents and experts on here - does anyone know about Crosfields glass production? Did they just do a bit of kitchenware?
