Welcome to Galaxy Glaze.... for the dreams and hopes of tomorrow


Thousands of years ago, people in the orient believed that the stars in the sky held our fate and future.
After ten years of tireless study I discovered a technique to convey the beauty of the cosmos through pottery.
I call it “The Galaxy Glaze”.
I hope that in the future the Galaxy Glaze will aid in the realization of a better world, achieved through
love and freedom.
My aspiration is that the Galaxy Glaze will become a beacon of hope for the future in these turbulent times.

Characteristics of the Galaxy Glaze


The array of colours displayed in the Galaxy Glaze are formed by the various metal elements in the glaze crystallizing under the extreme heat of the kiln. This process is designed to replicate the infinite twinkling of the stars. The particles of various metal elements in the glaze crystallize during a stage of gradual reheating after being subjected to extreme temperatures in the kiln (with highs of up to 1280°C).

Galaxy Glaze belongs to the group of iridescent crystalline glazes including others such as oil spotted black glaze (Yuteki Temmoku), Blackish “hare’s fur” glaze (Nogime Temmoku) and iridescent spotted black glaze (Yohen Temmoku).
While the black glazes’ (Temmoku) colour derives from two abundantly used metal elements, iron and manganese, Galaxy Glaze aims to have more complex crystallization by containing various metal elements with the exception of gold, silver, platinum and lead. This creates a wide range of beautiful colours and forms crystals which give an enchanting depth, more than the ordinary Temmoku. Similar to opals, all the crystals are different in colour and size.

The creation of the Galaxy Glaze required an in-depth knowledge of the field of pottery. Furthermore, it needs the skills to gauge changes in the environment, such as humidity and temperature, while simultaneously adjusting the kilns to these factors. This ensures the control of the firing and glazing process.

However, due to the unpredictability of the environment the process to combine expectation and reality still remains difficult, and presents a daily struggle for the artist.
No two Galaxy Glaze creations are the same. Due to the sensitivity and complexity of the glaze each item displays a unique array of colours and patterns, each as magnificent as a jewel.

As the glaze is formed through a firing process the finish does not peel or fade with time. This endurance of the pieces means that the items are also microwaveable and oven-proof.

The shapes of Tetsuaki’s ceramics add to the individuality of the pieces. The vases, bowls, utensils and tableware are created from his skills and wealth of experience. His masterpieces are second to none in quality and beauty.

Tetsuaki Nakao and the Galaxy Glaze

Interview from the magazine “Tottoto” Nov 2006, Vol 28 pp.12-13

The spring Galaxy Glaze is reminiscent of the tender shoots of green leaves.
The summer glaze replicates the blanket of stars on a clear summer night.
The autumn glaze is inspired by the autumn colours.
The winter Galaxy Glaze represents a blanket of snow and frost.
The Mutsuki glaze turns into a bronzed gold.
All these basic Galaxy Glazes conjure the image of stars in the universe. This unique sparkle is one of the exquisite charms of the Galaxy Glaze.


Chasing my dream: from scholar to potter

“I used to want to be a scholar, studying social sciences”
In Tetsuaki Nakao’s art there is always the theme of passing the message through art. His message was influenced by his philosophical studies at university.

Born in the town of Yamauchi, Takeo, in 1952, Mr. Nakao aspired to be a philosopher or sociologist.
“Student activism was popular among my generation and I was influenced by this. When I was young I wanted to be a scholar. However, once I became a university student, I realized that there was a huge gap between my ideal and the reality to being a scholar at university. At that time I had lost my dream and struggled to figure out what I actually wanted to do with my life. Soon after this I saw my father and other craftsmen working tirelessly at the workshop to create their pottery and then I decided I was going to be a potter. I left university and started to train and follow the family business. I still read a lot of books about philosophy, social science etc, and discuss ideas with teachers and friends from university.”
From his appearance, I got the impression that deep down, he is still more of a philosopher than a potter.

I wish to create pottery that captures the beauty of the universe.

I aspired to create a glaze that captures the bright lights and colours of the universe. This aspiration lead to my invention of the Galaxy Glaze.

Everything started when, at 32, I was diagnosed with retinal detachment. I stayed in the hospital for a year, unable to see anything. This caused me great suffering, both physically and mentally. I worried that one day I would be unable to create anything at all. One day an image of the stars in the sky appeared in my mind and the sparkle of the universe began to wash my depression away. I could feel the stars in my mind, behind my eyelids, and it made me believe that there was still hope that one day I would be able to see again.

I started thinking that if I could create a piece to show this, the extraordinary beauty of the universe, that there could be hope for another, suffering in the same way that I did.
This thought became my dream and this dream became my motivation.

Creating the Galaxy Glaze.

The Galaxy Glaze is the result of metal crystallizing after being heated at a high temperature (between 1200°C – 1250°C) in a purpose built kiln.
This is a type of iridescent crystalline glaze which Tetsuaki himself named ‘Galaxy Glaze’

‘As soon as I started my recovery from retinal detachment I began to read books about glazes and pottery from all over the world. I experimented countless times with different mixtures, continuously exploiting more and more data to further the research. I treated the project as a scientific experiment. It took 5 years to create the first Galaxy Glaze, and even more to perfect the end product.’

‘It is still a hard task, creating the Galaxy Glaze I envision. Unpredictable elements, such as the humidity of the kilns, have an important role in its creation.
The Galaxy Glaze was created after many years of research and experimentation, with great patience. When I finally saw it I was in awe.’

‘The Glazy Glaze is actually very similar to jewellery. If I take a ruby or emerald for example, their colours are different due to the refraction index. The colours differ based on the arrangement of the atoms. For this reason there are five different kilns for each colour in the Gyokuhou workshop.’

He (Mr Nakao) says ‘There are two sides to my work, the artistic side and the scientific side. Kilns are not always stable, so it is very hard to create a specific colour. You cannot give up, even when you feel you have no control of the kiln’s reactions.’ Almost as if he is a chemist. The crystallization of the glaze gives off an almost jewel-like beauty. It requires him to not only have a knowledge of the science but also the skills to predict the unpredictable. His journey to create the perfect pottery continues.

The message I passed onto Galaxy Glaze.

The Japanese painter Hiroshi Senjyu said in his interview that all the artists in New York are now on the edge of despair. Mr. Senjyu added, “After experiencing 9/11, the artists should have taken the role of alleviating pain from peoples’ minds and present the sympathy felt towards both the attackers and the victims. Yet, they lacked the purpose. After the 9/11 terrorist attack, art such as those created by Cézanne and Gaudí, widely recognised in history, encouraged and healed the peoples’ broken hearts. Art has been able to give hope and encourage people, as well as heal the mind, regardless of the differences which divide us; the border, religion and ideology.”

I indeed wish to pass on this message within Galaxy Glaze. To have love and liberty, take the same role as that of the art in history.
Mr. Nakao explains passionately, “Surely, I can do this by inventing a new glaze, never before seen in history.”

Looking abroad
“Beauty” is beyond borders.

Having looked at Mr. Nakao’s record of the prizes, I was astonished. Especially the number of prizes he received from abroad. China, Italy, Spain, France, the list goes on and on.

Mr. Nakao started to look abroad around a decade ago, after meeting Professor Zhang Shou Zhi (張守智) from China.
“The professor praised my art highly, yet I wasn’t doing great at that time in the public art exhibitions in Japan. I tried to sell my art, but no one wanted to buy it. I spoke to Professor Zhang. The professor advised me to send my art to European exhibitions. He said that the Japanese art culture is not yet open-minded enough to approve your art, but you would have opportunity to be recognised in Europe, where the art was developing. He encouraged me by saying “it is even possible for your art to be acknowledged as one of the best, when you aim high and put in enough effort.”

Soon after Mr. Nakao started sending his art to exhibitions in Europe. In 2003, he awarded ‘Prix de La Porte des Lions’ as well as ‘Prix Tricolore de la Paix de l’Art’ at the ‘Revolution in Art’exhibition at the Louvre Museum.
“I was fulfilled by knowing that my art had been awarded, because it was the moment I could feel that my message was being passed on. ‘Love and liberty’ had reached to people beyond the border from where I had created it. I could feel that what I had been doing and the time I had spent striving towards my dream had meant something.”

Meeting Iemoto (current Grand Master of tea ceremony).

mizusashi When you hold any Chadougu (Japanese tea ceremony utensils) from the Galaxy Glaze, you will be surprised. They are extremely light.
Mr. Nakao says “Tea utensils like Mizusashi are used to hold water. I always think about how much it would weigh if it was filled with water, used as a tool, so people can hold and lift it.” Not only is his art beautiful, it has a keen aesthetic and sense of consideration for the user.

“I wanted to blow a new wind into the world of the traditional tea ceremony. The Japanese tea ceremony is about ‘Ichi-go ichi-e (a once in a lifetime encounter)’. I was touched when I met Iemoto of Enshu-ryu(one of the historical schools of tea ceremonies) when I was struggling to create my tea utensils. 5 years ago, I had an opportunity to meet Iemoto after my acquaintance who introduced him to me warned of the likely possibility he would be disapproving of me and my art. He also suggested that I give up trying to create my tea utensils if this was the case. Iemoto has been consulting me on tea utensils ever since.”

The tea utensils in Galaxy Glaze were used in the special teahouse at The 2005 World Exposition, in Aichi, Japan, and are used in tea ceremonies still held by Enshu-ryu nowadays. “When you create something new, people often do not acknowledge the value immediately, but this will change as the time passes. When you keep challenging yourself, you will eventually create the one that will be remembered by history, even if it’s 100 years, 200 years later.” Iemoto encouraged me.
Mr. Nakao is enthusiastic to continue challenging himself and his journey.
