焼杉 

@marthale7 Yea that is why I am watching as well, I will be doing oak barrels.

I think boiled linseed oil is the traditional finish.

Maybe linseed oil. Edit: yeah see above linseed oil also hardens which makes the finish last longer.

Boiled linseed oil works very good. The oil sets after a week

Cheap and fast!

Yakisugi is the traditional non_westernized term to use in case you were curious 😀

You do know that wood burns right?

Damon Lam this shape works as a chimney, due to pressure difference it gets more air- thus oxygen from the down side.

And that's how it's done!

Also, he told me the wood is kept drying in the sun for at least 14 weeks, so at this point the cedar is really dry and burns instantly

I tried it myself with well dried larch. There is some thin wood put in with the newspaper, if you watch the video colsely. It works like a charm! You wouldn't believe, how fast you have a blazing furnace!

Yes. Pine and cedar yield the best results. Hardwoods, such as oak, maple, and hickory, do not fair so well.

Solution: Linseed oil?

No

U can use hemp cord, soke it in water for 30 minutes then it will withstand the heat for this technique.

I think he's using some chain and maybe some springs to keep it in tension? And then metal wedges to increase oxygen flow

Cedar!

No need to protect the backside, as it's not exposed to the weather

@@ximono - Well it's still exposed to humidity, no?

@@luclafor Yes, and humidity is fine. Wood "breathes". Its cells absorbing water from the air when relative humidity is high and releasing it back when the air is dry again. I'm not sure how the charring affects water transportation through the boards, but if you paint the boards with a (relatively) impermeable paint, typically based on plastics, the back side should be unpainted so that the wood can "breathe". Otherwise it will rot. Which is why there should also be an air gap behind the boards. Even if you were to use a paint that's (relatively) permeable, like based on linseed oil or rye flour, it's just not necessary to paint the back side. Paint is mainly an esthetic element, while it protects the wood from slooowly breaking down from UV rays. Painting the back side would be twice as expensive and twice as dumb :) For yakisugi, it's twice as much work.

@@ximono - Oh ok then, if you say so. I guess you're an expert. Thanks

Just piece of wood or cardboard for burning.

Magic.

From my understanding , it is quickly burning and vaporizing the volatile compounds and resins in the top surface of the wood, starting at the very bottom. And as the fire goes upward it continues somewhat evenly as the fire doesn't penetrate very deep.

Jenene Try centuries :b it's one if not the most rot and bug resistent ways of treating wood known to man.

This type of wood can last for centuries as the coal finish inhibits mold growth. Usually oil is applied afterwards to seal it further.

So how does it 🤷‍♂️

nope, the sides are left unburned

@@jjcruzflorin te referis a los costados de la tabla o a la otra "cara", la que queda para afuera? Que es lo que el señor no quema? Gracias por subir este video, es uno de los mejores que he visto en RU-vid mostrando la tecnica hecha por un artesano japonés de raíz!

haha, wtf? I took that video when I went to Ushimado in 2013!

CJ Schmitt hahahahaha, guess what? I went there to study , and actually Japanese government very gently paid for all my expenses. I’m a very lucky Mexican 😘

@@jjcruzflorin that is fantastic man!!!! Gratz! Great culture to go and study under!
