Big blue jar

Can anyone help identify this big heavy jar?
It's 28.5cm tall, 22cm diameter.

It could well be Denby.

I'm not finding anything this shape under Denby searches - only French glass jars and Hornsea heirloom jars.

They did make various containers for industrial use, that generally weren't marked.

Thanks DD. I can't imagine what this might have been used for. It weighs over 4kg when empty!
Any ideas regarding age and materials? I'm thinking ironstone, given its weight :D

Ironstone is a type of earthenware and not very heavy. I imagine this is stoneware.

I have always thought such items were late 19th into the 20th century. Many products were sold in pottery containers rather than glass e.g. jams and marmalades and besides retail were made for industrial use. There were many factories producing such items but the blue glaze is something that tends to be associated with Bourne Denby in my experience.

Thanks. I've only seen similar containers in clear or brown shade glazes, so it's good to be able to pin it down a bit.

I don't recall knowingly seeing stoneware pots by Lambeth potteries such as Stiff and Doulton in blue but, as these items are often not marked, you never can tell.
