Yamashita-san's philosophy

Yamashita-san discovered and learned pottery thanks to his father-in-law, a researcher at a ceramics research institute.

He has been perfecting his craft for more than 30 years.

When he makes his pottery, he empties his mind and focuses on his work. He says he thinks of nothing at all.

He loves seeing his creations used in everyday life, and he considers his pottery everyday objects. He does his utmost to keep his prices affordable with the sole aim of having his bowls used in our daily lives.

Although Yamashita-san's bowls are reasonably priced, they are all handmade by himself, using the traditional clay and glaze of the region.

I was won over by his philosophy, and I am very proud that he is part of our partner artisans.

above, I'm posing with Yamashita-san during our 2nd meeting in May 2019

• he extracts clay near his workshop and cleans it by diluting it in water to remove pebbles and impurities, then lets it dry
• kneading: Yamashita-san kneads the clay to release the air bubbles and make it homogeneous.
• throwing on the potter's wheel
• trimming: he lets the bowl dry for a day, then turns it over and shapes the foot of the bowl
• first firing: he fires the bowl at 800ºC for about 8 hours. The bowl's size decreases by 20%.
• glazing: a mixture of crushed straw ashes, charcoal and feldspar. Yamashita-san dips the pottery into the mixture.
• glaze firing: in Yamashita-san's kiln, this takes another 7 hours of firing at 1260ºC.

In the image below you can see the very dark mixture of ash and stone, which will form the bowl's glaze and turns white when fired:

It is Yamashita-san himself who makes the glaze for his pottery.

For the final step, there are two ways to fire the glaze:

• oxidation firing: oxygen is allowed to enter the kiln.
• reduction firing: no oxygen is allowed into the kiln, and the flames seek out the oxygen present inside the glaze, changing its chemical properties and its appearance.

the kiln temperature is 1260ºC during the glaze firing

History of Karatsu pottery

Karatsu is a port town located on the island of Kyushu, in the far south of Japan.

Thanks to its geographical location, it has been in contact with China and the Korean peninsula since ancient times. And it is thanks to this outside influence that Karatsu was the first region in Japan to make bowls with a glossy glaze.

Karatsu pottery (唐津焼, karatsu-yaki) became famous throughout Japan in a very short time.

At the end of the 16th century, Karatsu's matcha tea bowls were recognized by the great tea masters as one of the three predominant bowl styles, along with Raku pottery (楽焼, raku-yaki) and Hagi pottery (萩焼, hagi-yaki).

When I asked Yamashita-san whether he intended to pass his art on to his children, he told me no, because his clay vein is exhausted.

He showed me this photo, telling me "I have enough to keep working until I retire, and after that it will be over":

the keys to Japanese aesthetics

As Yamashita-san explains to us, there is a large element of chance in his creations.

When he fires the glaze of his bowls, for example, the result can vary depending on where the bowl sits inside the kiln due to heat variations.

Of course, he has no control over how the glaze flows either.

It is a deliberate choice to keep this element of the unexpected, and for me, that is what truly makes the charm of Japanese pottery. Not everything is standardized like in industrial production.

The slight irregularities of each bowl give them a different character and personality.

⚠️ Usage tips from Yamashita-san:

• Before first use, I recommend soaking your bowl in water with 1 or 2 tablespoons of flour for 5 hours. The starch in the flour will act as an extra sealant to protect your bowl.
• The appearance of your bowl will evolve over time: it will craze and develop a patina. Take good care of it and it will become even more beautiful and unique.

the final result

This off-white bowl, with a glossy, smooth glaze, is elegant and minimalist.

I love the details: the foot, which is unglazed, is rough and earth-colored.

My favorite little detail is the center of the bowl's bottom: Yamashita-san has drawn a whirlpool shape, which collects the suspended matcha tea and offers a final sip that is slightly more concentrated and very pleasant.

I hope you will enjoy sipping your daily matcha from this artisan Karatsu bowl.

I am very happy and proud to be able to present this bowl by Yamashita-san, which is very affordable for craftsmanship of this quality.

The colors differ slightly from one batch to the next, so if you like this bowl and want to make it yours, I recommend ordering it as we have a limited quantity of these bowls.

On behalf of Yamashita-san and myself, we wish you an excellent tasting!

Differences between Japanese pottery and Western pottery

First of all, the material is different: while we use a mixture of earths (clay, marl, silica), most Japanese potters use only clay.

Since we pick up the bowls with our hands to admire them before bringing them to our mouths to enjoy matcha tea, great attention is paid to the texture of the bowl and how it transmits heat.

The other very different element is that in the West, we often use a set of identical cups, whereas in Japan people often have many different cups. Originally, in the tea ceremony, it was the host's responsibility to choose a selection of cups that go well together to please their guests.

Finally, the Japanese find beauty in the distortions and "accidental" irregularities of the pottery and its glaze. Wear rounds the edges of the bowls and beautifies them. This is the concept of wabi-sabi.

Preparing matcha tea

When preparing matcha tea, leave most of the bowl empty to admire the color of the matcha and the pearly white, during your own matcha tea ritual. Notice the texture and sheen of the matcha.

This artisan bowl also has the characteristic of a summer bowl, as its open rim allows the heat to dissipate more easily.

The bottom of the bowl is rounded and its capacity is particularly suited to a preparation for 80-100mL.
