The "Ruskin-like" so-called Crown Lynn trickle glaze: Was NOT made by Crown Lynn!!

This forum thread has a plausible attribution for these type of pots that we see labeled Crown Lynn all the time. That they should be English makes sense, as there seem to be quite a lot in NZ. 99% of our pre-war ceramics came from the UK. The key to this is the name JAMES PLANT.

If you have a look at this auction, the pair of pots decorated in the Gouda manner are of a form I have seen in NZ in the 'Ruskin-like glaze' also. Its all falling into place...

In fact, its one of the ones illustrated on this very august site:

Quite by chance one of these beautiful vases came my way yesterday and there is a mark in an oval surround on the base.  I posted about it on Facebook.  I think it's an exciting find, but I can't hook it up with any of the links that you posted T&C.  There was one on Trademe with a silver collar that was hallmarked 1920 and can be seen on the Pinterest page.  Definitely points to British and they mention the collars on the 20th Century site.

Edits to add that I've posted pics on the 20th century site.

Ev, I have seen the replies on the 20th Century Forum, which leaves us no closer to identifying the maker, other than to underline that they were not made in New Zealand. Maybe this is one of those rare occasions when, in the spirit of intrepid inquiry - and for the greater good - you could justify reaching for a fine grained sandpaper and gently abrading that glaze that has so inconsiderately obscured the mark?

Oh wow I hadn't thought of revealing the mark in that way T&C

I've checked out all of the online M marks for British Potteries and other relevant marks without any luck. The odd thing to me is that I've never seen the shape of the two vases in the original post on 20th Century, but the glaze matches perfectly.
I will ponder the best way to attack the glaze ..... eeeek

First grinding experiment failed, as the grinder had black paint on the wheel and this was transferred onto the glaze ..... oh no!!!
It wasn't a cheap pot by any means, so I have to find a bench grinder that has only been used for pottery.

Ev - I would use hand sandpaper only. It might take ages, but you have far more control and you don't run the risk of wrecking the pot. The glaze here is not too thick, so I don't think it will take an inordinately long time.

Thanks T&C that was my husband's suggestion as well.
I've used grinders for years and years, but only to remove excess glaze which is a simple process.

Ev do you have a Dremel or similar? Aldi sometimes stock their copy Dremel and sometimes sell a compatible accessory kit that has dozens of pieces at a fraction of price the Dremel branded ones. This might give you the combo of hand held control and electrical power. While the rest of the fam were in the Bunnings gardening section on Saturday I was drooling over the Dremel display.

No I haven't one of those Tony, but I have seen ones that potter friends use and they are a dream tool. I'm sanding the mark with an electric sander now and it's going to take a while.

Lappie is getting a new Hard Drive, so I bought a Dremel to celebrate
Watch this space ..........

Still no wiser are we Ev? May I suggest the very fine grained hand sandpaper again? You would smooth the clouding effect of all the fine scratches and may make it clearer.

I will try T&C, but I don't hold out much hope.
A comment on the 20th Century site made me feel unwell ...

I wouldn't worry about that Ev. You've given it a go and still got a very nice vase, that may yet reveal its secret. Your use of the dremel was quite skilful all things considered. I couldn't have done it as well.

I had a comment left on a photo of this ware on Pinterest

I have several of these. James Plant Pottery.

I have asked for more information.
Google turned up a better link on the 20th Century site for James Plant & Sons, but I am still frustrated at the little information available.

Fine sanding of the base mark has not been fruitful to date.

More evidence that these are James Plant pottery:

That listing on TM is exciting as I haven't seen that shape before and it looks like JP is on the base?  The shape is similar to the Worthpoint listing, but not an exact match. How wonderful to know that they marked their work Made In England by Jas Plant. Thanks T&C

No problem Ev. They are a close enough match for me to believe they are from the same mold.

Oh my .... tuitua has put a close up of the mark of her pot and now it looks like 113 or 115 and not like a J P at all.

Apologies for my quick comment regarding these shapes, as I just put them side by side to compare and I agree with you that they are a match !!!

James Plant

A shape I've never seen just turned up on Facebook and it has a stamp on the base.

Can anyone decipher the stamp please?

I get "MADE IN", six letters plus a space, but the other is indistinct.

At first look the last letter looks like A but maybe not.

There is almost enough room for England, seven letters, but certainly not for New Zealand.

I googled combinations with Ruskin pottery plus a variety of country namees with no luck. Then tried with blue purple pottery plus various countries but still no luck.

Pretty sure there is not enough room for it to be Australia.

The mark looks like it is Made In Germany and is like the KPM Krister Porcellan Manufaktur stamps. I haven't been able to find anything else they made in this style and glaze to confirm this.... yet.

Devonmoor has turned up as another possible maker for this ware and some shapes and glazes look familiar, but they appear to be stamp Devonmoor England more often than not.
