Large Glazed Stoneware Vase From Japan, 1950s/60s

A large glazed stoneware vase...
Titled "Flower of a Tube" (a translation I'd like to give you...)
By a Japanese artist...
I think I translated it correctly as Daikan...
Signed in the stoneware (see photo)... I
t's a unique piece...!!
A very interesting piece...!
Roll-shaped, tapering to a point...!
With a lot of work done in the mass...
Wheel-thrown and then worked...
With scalpel cuts in the clay after glazing... With what look like additions of stoneware in certain places...!
Deformities...!
In the Raku style...!
Worked like superimposed and crushed discs...
With scratches...!
With the final green glaze poured horizontally...!
And so firing it horizontally was quite a feat...!
It's even partially glazed on the inside...!
It's very thick, 3 to 4 centimeters at the rim...!
In perfect condition...!
With its original box...!
Weight... over 6 kilos...
For your information, I didn't have power scales when I made the ad; I'll correct that later...
