Interesting pair of vases - James Plant & Sons ?

I have just acquired a job lot of ceramics and I have a few items I can't identify.

This pair of vases is one of them (think it's a pair) - if anyone has any idea about their origins I would be most grateful.

I though European - German/French/Belgium?

These are almost certainly James Plant art pottery.
These blue glaze ones turn up in various shapes and sizes, sometimes with silver collars.
but I have only ever seen a couple actually marked.

I can't find any examples of these ID'd as James Plant. All the examples of JP&S appear to be heavily patterned.

All I can say is, that there were a pair of these blue vases in a local antiques centre,
with the normal Plant mark, but when I took my camera in to photograph
them they had unfortunately sold.

I trust Denby on this.

So many of these early 20th art pottery vases are unsigned that when you get any attribute and a marked pair they disappear quickly. Not sure why so many never got marked, it could be the taste of the time, what retailers requested or some other reason. But If we know James plant made an identical glazed vase then that is good enough for me. It is the glaze in my opinion that denotes maker in these period vases not the shape. Most shapes are based on Chinese originals and can be very generic, that and the molds got sold and passed around leading to many makers making the same thing. Glazes are chemical and kilm temperature recipes, they tend to be maker specific and not passed around.

That all sounds logical. I never really doubted the greater knowledge on here - it was just that I can't find a single piece online that is marked. The fact, as you say, that retailers requested unmarked items is something I never considered. I guess these could have bought at Woolies in 1930 :)

I bought them as part of a collection that included Friberg, Royal Copenhagen, Royal Lancaster, etc - so the person who put the collection together probably knew what they where buying… but sadly I bought the collection from a furniture dealer who did a house clearance and so I can't ask where they might have come from.

I have just spotted these on eBay - again unmarked but with the silver collars - 152560485943

Yes they are the ones. Sometimes they were attributed to Devonmoor.
The other problem is James Plant used an overglaze ink stamp which
would easily rub off shiny surfaces, unlike the "Gouda" wares which
are matt.

I guess if you could see the hallmarks on the silver it might give a clue - certainly proves their British.

Not absolutley, but would certainly give  a date.

Things were imported, and had hallmarked silver embellishments added later.

Hi there I got this beautiful vase yesterday by chance and it has the same glaze as the first post. These are seen from time to time on New Zealand auction sites, so I'm familiar with the glazes and shapes. This one has a stamp on the base in an oval surround with perhaps an M inside. Most of the vases I've seen are numbered. Any help would be appreciated as I'm not familiar with British potteries.

Well, this is certainly the same manufacturer, and the first piece I have seen
with a mark other than the numbers.
A pity it is so indistinct, maybe "M" in an oval?

The jury is still out on these!

I still haven't found anything new - there where two pieces sold at auction with two Plant and Sons Gouda vases and they where described as 'Linthorpe style'

Yes, same stuff, there is quite a bit of it around, the shapes and glaze point to
early 20thC art-pottery, but by whom?
It might even be bought-in continental at a push.

The marked piece stil intrigues me, could it even be CM joined?

Thanks everyone, at least this mark is out there now and hopefully it will be identified in times to come.

I have tried to reveal the mark using a Dremel

Hmmm not sure that was a good idea!
It just wanted photographing from the right angle,
with no flash and glancing daylight.
