A Conversation
Between a Collector and a Scientist:
How I Fell in Love with Yuan Blue-and-White Porcelain
By Dr. Jeannie Yi, New York
Although my home is filled with all kinds of decorative
vases and jars, I had never collected Chinese ancient art.
Near my home is a Hong Kong supermarket that often sells
Jingdezhen porcelain. Whenever I saw a beautiful piece while
shopping for groceries, I would happily bring home another
little “treasure”—perhaps a blue-and-white porcelain vase.
When I first met Dr. Jeff Ye, I was like most people. I
believed that determining whether an antique was genuine
depended entirely on the trained eye of an expert—on
experience, intuition, and stories. To be honest, some
reproductions even looked prettier to me than the authentic
ones. Besides, even if I mortgaged every townhouse in my
neighborhood, I still could not afford a genuine Yuan
blue-and-white masterpiece—the king of Chinese porcelain.
Why spend so much energy worrying about authenticity?
That began to change in April.
We had been invited by my good friend, Professor Rong Liya,
Dean of Boston International Business School, to attend one
of her events in Boston. Perhaps it was the academic
atmosphere, but during the trip Dr. Ye decided it was
finally time to teach me what Yuan blue-and-white porcelain
really was.
He pointed to a blue-and-white jar on his phone and asked,
“Do you know how these rust spots were formed?”
How could I possibly know? I assumed they were simply the
result of age.
Instead of telling me how much the jar was worth or which
emperor’s reign it came from, he asked me to look closely at
the tiny dark brown spots scattered across its surface. In
some places, they even appeared to have slowly dripped
downward over the body of the vessel.
It was fascinating.
I remember saying,
“The rust spots were actually dripping down the jar.”
The more I looked, the more intrigued I became. After all,
here was a porcelain vessel that had survived for more than
seven hundred years.
But I later realized that what Dr. Ye saw was not simply a
seven-hundred-year-old object.
He saw a chemical reaction that had taken place seven
hundred years ago.
Then he said something that completely changed my
perspective:
“Sumali cobalt is simply a mineral. Under high temperatures,
it turns blue.”
No mysterious formula.
No secret family recipe.
No mysticism.
Just a mineral.
Sumali cobalt.
Imported from the Middle East.
At that moment, the whole world suddenly looked different to
me. My mind immediately went back to my high school
chemistry class.
Diamonds are fundamentally carbon.
Iron ore is fundamentally iron.
Sumali cobalt ore consists primarily of cobalt, mixed
naturally with iron, manganese, and other trace minerals.
Ancient potters had no laboratories. They knew nothing about
chemical elements. They simply ground this mineral into an
extremely fine powder, mixed it with water, painted it onto
the porcelain body, and fired the vessel in a kiln at
approximately 1,300°C.
And that is where the real miracle occurred.
Cobalt turned into its deep, luminous blue.
Iron created what we now call “rust spots.”
Meanwhile, the glaze—a thin coating applied to the clay
body—slowly melted in the intense heat and finally
solidified into a transparent, glass-like protective layer
that permanently sealed everything beneath its surface.
Dr. Ye said,
“Glaze is essentially a layer of natural glass fused onto
the surface of porcelain.”
That sentence astonished me once again.
I had spent decades buying and admiring porcelain—both
genuine and imitation—yet I had never truly understood what
I was looking at. I had always assumed that artisans simply
painted directly on the surface and then fired the piece.
Dr. Ye explained that this was not how genuine Yuan
blue-and-white porcelain was made.
The cobalt decoration was first painted directly onto the
porcelain body.
Then it was covered with a transparent glaze.
Only then was the entire vessel fired.
After firing, the glaze became a layer of transparent
natural glass.
The blue decoration was therefore not sitting on the
surface.
It was quietly resting beneath the glass.
Looking through that crystal-clear glaze, the blue appears
as though viewed through a clear lake of water—a soft
translucent tone the Chinese often describe as duck-egg
blue.
Dr. Ye then returned my attention to the rust spots.
“Why,” he asked, “do some of them look as though they have
actually flowed down the vessel?”
Because at approximately 1,300°C, the glaze is no longer
solid.
It becomes a slowly moving liquid.
Imagine placing a drop of honey on a sheet of glass.
It does not immediately run.
It slowly creeps.
The glaze behaves the same way.
If the
original Sumali cobalt mixture contained a higher
concentration of cobalt and iron in certain areas, those
minerals would migrate slightly as the molten glaze slowly
flowed during firing.
As a result, some of the darker blue areas appear to stretch
gently downward like a drop of ink, giving the impression
that the iron-rich pigments had flowed down the surface.
That was exactly what I saw in the Yuan blue-and-white jar
displayed on Dr. Ye’s phone.
I was completely amazed.
Even more astonishing was the realization that all those
chemistry lessons I had memorized in middle school suddenly
came alive.
What we see on Yuan blue-and-white porcelain is not merely
pigment.
It is the preserved record of liquid glaze flowing seven
hundred years ago, carrying iron-rich minerals that
decomposed and recombined under the intense heat of a
1,300°C kiln.
Those reactions created the remarkable rust spots that give
the flowers such depth, richness, and vitality.
At that moment, art became science.
And for the first time, I truly began to understand
porcelain.
Of course, not completely.
Dr. Ye emphasized that authenticating Yuan blue-and-white
porcelain requires evaluating many additional factors,
including the clay body, glaze composition, cobalt
chemistry, oxidation layers, aging characteristics,
microscopic structure, and more.
As he often summarizes:
Macroscopic Observation + Microscopic Analysis = Form &
Construction + Decorative Techniques + Color Authentication
+ Aging Characteristics + Body, Glaze & Foot = Form +
Pattern + Color + Age + Body + Glaze.
What stayed with me that day was something much simpler.
Today, we are still able to witness that single firing seven
centuries ago. Since that day I fell in love with the
Chinese porcelain! |

At the beginning of 2026, a moment of
particular significance quietly took
place in New York, a city where art and
finance converge.
After years of anticipation
The International Institute of Art
Asset (IIAA)
was formally established.
Its importance reaches far beyond the
founding of another institution. For the
first time, a clear structural pathway
emerged for Eastern art to enter the
Western world—not merely as cultural
display, but as a system grounded in
valuation, legitimacy, and sustainable
commercial return. What had long existed
as aspiration was now becoming reality.
Throughout human history, the forms of
wealth have continuously transformed:
from gold and silver, to land, to
financial instruments, to luxury goods.
Yet among all these, only collecting
truly connects us to the roots of
civilization itself.
Collecting is often misunderstood as a
gesture of wealth or status. In truth,
it is an act of remembrance. Through
porcelain, jade, and bronze, we glimpse
the lives, values, and spirits of our
ancestors. Each artifact is not merely
an object, but a living fragment of
time.
Sitting across from me during this
interview was Jeff Ye, one of the
five co-founders of the International
Institute of Art Asset and the director
responsible for its antique and museum
collections.
In his hands, he held a remarkable
imperial
“Dragon Plate,”
inscribed with the phrase
“Mandated by Heaven.”
The object was overwhelming in its
presence.
This was not possession in the ordinary
sense. It was guardianship.
Jeff Ye owns thousands of such
treasures. His collecting journey has
taken him across China, from academic
research to remote regions, from
established markets to newly discovered
sites. Whenever news surfaced of an
unearthed artifact, he would go—without
hesitation.
What he collects is not defined by
money, but by responsibility.
Responsibility to history.
Responsibility to civilization.
This is where collecting transcends
wealth
and becomes a form of cultural
stewardship.

The glazed glass of the Spring and
Autumn and Warring States periods is
breathtaking in both color and form.
Perfectly round, crowned with a dragon,
it carries a blessing: auspiciousness,
peace, and harmony.
It is, in essence, China’s gift to the
world.
And it is also the spiritual origin of
the Art Asset Institute—
the mission of the descendants of the
dragon:
to protect, transmit, and honor
civilization.
For Jeff Ye, collecting has never
been defined by money.
It is defined by whether one is willing
to bear responsibility for civilization
itself.
When the Rockefeller family and the
Rockefeller Foundation traveled
repeatedly to China, they were certainly
not seeking oil deals or architectural
investments. They were searching for
treasures like those now resting on Jeff
Ye’s table—fragments of history that
allow future generations to see, with
their own eyes,
stories that began thousands of years
ago.
If collecting carries a certain
aristocratic spirit,
then this spirit takes many forms.
In Jeff Ye’s “aesthetic style of
collecting,”
I saw not luxury, but guardianship.
A guardian who has spent more than
thirty years
preserving cultural memory.
While managing real estate development
projects, he carved out rare time to
enter China’s once chaotic antique
markets, patiently watching them evolve
into systems of order. Again and again,
he searched—sometimes close to home,
sometimes across great distances
—for artifacts that carried the breath
of history.
At first, like many collectors, his
questions were simple:
“Is it beautiful?”
“Is it valuable?”
But gradually, his questions became
deeper:
Where did it come from?
Does it align with historical logic?
Can it withstand scientific scrutiny?
He once asked me quietly,
“Can its materials, craftsmanship,
patina, oxidation, perforations, and
color transformation endure both
scientific testing
and experiential judgment?”
I had no answer.
Though my own family had passed down
certain “treasures” through generations,
they lay untouched in cabinets
—unpriced, unrecognized, untradeable.
Jeff Ye, trained in chemistry,
understood that intuition alone was not
enough.
For collectors and enthusiasts alike, he
developed a rigorous system:
a twenty-criteria methodology for jade
authentication that moves from instinct
to science—
now known as the “Ye Standard.”
He said:
“Forgery in antiques is actually a false
concept.
Only time leaves irreversible marks.
To claim something can be perfectly
forged
is to claim time itself can be reversed.
Anyone with basic logic knows this is
impossible.”
In Jeff Ye’s system, the first judgment
is never data—it is breath.
Not reports, but whether the object
possesses a soul.
He believes in eye connection.
He believes in touch.
He believes in the intelligence stored
within the body
through years of experience.
For him, collecting is not ownership—it
is encounter.
A meeting between human and artifact,
guided by fate.
Much like love itself: different in
form, universal in essence.
That love pushed him to unite
aesthetics, history, chemistry,
microscopic observation, and instrument
testing.
To synchronize intuition with science.
In his world, collecting becomes a true
“cultural science”—
and an inheritance of love.
Not merely feeling,
but a civilization authentication
system.
From instinct and romance,
to verification and responsibility.
Like glazed glass itself,
his life has been shaped by fire—
again and again refined,
until clarity became light. |
