Chinese or Art Deco studio vase needs ID

hello together !
a friend of mine asked for help to identify this stunning 1930s vase.
he bought it in the city of Münster, in the north-west of Germany.
i have no clue about the mark, even not if it is of german origin.
it is appr. 35cm tall.
hope someone can help or give a hint....!
Thanks Tom.

Can they be certain of the 1930s date? On first sight I thought it was c.1900 Chinese, but looking at the JT (or TJ) mark I think it's Chinese-influenced. Might be Dutch but that's purely a gut feeling.

1930s was just an impression...date of making might be different..

Is it porcelain, stoneware or tin glazed?

That piece is not in my house.
I remember feeling inside it was handthrown, but not sure about that either...
And without chips, quite tough material, i think. Probably stoneware.
Even not sure about the clay color...
"tin glazed" ? i did not deal with the chemical subject, so do not know how this dark white glaze was created…
Sorry, i thought the piece could be identified by mark....
Thanks Tom

The mark is just one clue, and so far I haven't been able to trace it. It would really help if we knew the composition as that would narrow down the country of origin.
If it was tin glazed earthenware (which is quite soft) it would point to a Dutch delft origin.
If it was porcelain it would indicate a Chinese or Japanese origin.
It it was stoneware it would indicate a fairly recent date, or it could be Vietnam or Korean origin.

The thinness of the base indicates it's porcelain as that is much stronger than a tin-glazed earthenware.

If it was Dutch delft or Chinese/Japanese it could be a special piece and it would be worth taking it to a specialist appraiser at one of the auction houses.

It's possible it's early Japanese, copying Chinese. Hence the odd mark which is an attempt at a Chinese character:

Thanks for your informations.
I see i have to take a very closer look to that piece again and to make more detailed pictures, once i visit this friend again. will come back to this piece at a later point.
a last question. if my memory is right, i felt inside ripples, which indicates a hand-thrown piece.
if so, then it could not be porcelain, right? cause porcelain is a cast material...?
thanks again,
Tom

There's no reason porcelain can't be thrown

Parian ware, which is sort of a porcelain in a watery slip form is case, but porcelain can be hand thrown (check out Edmund de Waal's hand thrown porcelain pots). The Chinese throw them quite thickly and then shave them down on the outside, on a wheel, giving a very smooth and thin pot. But on some you can still feel the ripples, especially on the inside.

oops typo, 'cast', not 'case'
