Tankard Jug marked "30" (715 or 816 type)

I've always wanted a big white jug and almost overlooked this monster while I was fussing about a Royal Oak canister on the next shelf at Kamo SPCA.
I think it's actually bigger than I wanted at 8 inches high and looking the whole foot!

I've looked through the topics and have not found this one.

A jug of the "715" type, white, and big.

The only marks are "30" and "Made in New Zealand"

I'm not up with the play on these jugs. It is in perfect condition, so I'm presuming vitrified but the staining on the foot ring may indicate otherwise. I've seen "big" jugs in the topics marked 20 but not a 30.

It would be useful to have the measurements for all the "715s".

Is this a "Hotel Jug", "Water Jug", "Milk Jug", or something else?

What a wonderful find Jeremy. These are so well designed and perfect to use.
I've found quite a few small ones lately in various sizes.
The records read:
715 -Tankard Jug
The smallest is 715/0, then 715/01, 715/10, 715/20, 715/30, 715/40, 715/50,
There is also a teeny 1621 in the same shape.

There aren't any measurements, so it would be great if we could add them in here.

Not sure if the 715 is vitrified, as there are three sizes in the records for 816 that refer to the 715 shapes:
816/10E - as 715/10
816/20E - as 715/20
816/30E - as 715/30

The 800's seem to be vitrified records, though I have never seen a jug with the numbers 816 on them as they usually have just the size on the base.

Val Monk has a great post about these jugs on her blog -

Please note that there is one that has Vitrified on the base.

The cups in the Advert. are interesting.. two 'railway cups' with a skinny vitrified between them?

Not sure if I follow your thoughts Kat, as everything in that article is Vitrified ware .....
If only they had put the shape numbers for everything there!!

Yes it was an amazing find, Ev. Cost $8. Hospice has same for $40!
I checked Val's blog before posting. Thanks for all the extra info.
You wrote that the 816s had only the size marked so maybe that's what it is.

I've changed the title to make it easy to find.

Looking at the vitrified jugs Jeremy and I see there is a 6625 - 715/30 vitrified
and 6066 - 715/30 Tankard E/W.
Which do you think this is please?
I must get photos of all of mine and try to work out if earthenware or vitrified.

The condition is spotless which would suggest vit.
But the staining on the footring might suggest otherwise.

If it was stained through/beneath the glaze, as many seem to be, then I would expect E/W. And if crazed then definitely E/W. As I say, this is perfect.

I'll have to wait 'til I get back up north to look at the body, check the footring and see if it cleans up with chemico.

I will add this to the Four Digit Jugs Gallery as a 6625 thanks Jeremy.
How much liquid would it hold in litres?

Just over 1.5 litres.
