Wonderful Wood Works using Paulownia Crafts

Wonderful Wood Works using Paulownia Crafts

  • Woodwork Products Deadline : Nov 04,2019
  • Paulownia drawers are well known for being a gift presented to newly weds.
    Paulownia wood has excellent properties, making it useful in applications such as insect / mold repellent, humidity control and thermal insulation. Due to Japan's climate being hot and humid, such drawers have been essential for keeping clothes in excellent condition.
    We are looking forward to receiving product plans for ideas which make the most of wood works Kirisyou Nezu's wood working techniques!
Kirisyou Nezu (Paulownia Woodworks - Nezu) Kirisyou Nezu (Paulownia Woodworks - Nezu)

Gunma Prefecture, Tone-gun, Minakami-cho, Tsukino district. Founded in 1917, Kirisyou Nezu has been in operation for three generations. The company has continued to work, spanning generations and it is the last remaining specialist paulownia woodworks in Gunma.

Skills which have been passed down from generation to generation have gained the company a reputation as a repair shop haven for all things paulownia. Many people have confidence in thinking "Nezu will be able to do this!", and counting on their skills.

At Kirisyou Nezu, the craftmen do not hesitate to devote time and effort into the repairing paulownia drawers. They also carry out wood fabrication on the side, and are repared to overcome any challenge to realise the potential held by paulownia.

Up until now, they have made various products such as chopping boards, speakers and brief cases.

 

This time, we would like you to come up with a wide range of product plans which make the most of the unique properties of [Paulownia] and the woodworking skills of Kirisyou Nezu!

<Functional Aspects> 

  1. Lightweight: It exhibits the lowest density of all Japan-grown timber.
  2. Thermal Insulation: It has excellent thermal insulation properties and is commonly used for wooden flooring.
  3. Humidity Regulation: It has excellent humidity resistance and is thus used in items such as boxes for insense.
  4. Acoustic Properties: There is a lot of space between the wood fibres, making the wood highly porous and giving it excellent acoustic properties. Paulownia has been used from long ago to make instruments such as the biwa and koto.
  5. Insect Repellent / Anti-Mould Properties: The paulonin, sesamin and tannin contained within the wood gives it insect repellent, antibacterial and preservative properties.

<Natural Properties> 

  1. Due to it being soft, it scratches easily
  2. Due to it being lightweight, it is not particularly strong
  3. It is hard to remove stains caused by oils and other substances

■ Methods of Paulownia Woodworking [Jidaiyaki Finish (Burn & Stain Finish)]

Paulownia oxidises as it ages, causing it to discolour and turn brown.

This discolouration occurs due to paulownia being a natural material, and is proof that the furniture has been used over a long period of time. However, it can give of an old, weathered impression.

Kirisyou Nezu has a technique up it's sleeve known as [Jidaiyaki Finish] which is capable of semi-permanently preventing oxidisation of the wood surface.

The secret is to rub wax into the wood's surface when it is being finished. Wax is rubbed into the wood's surface by gently and steadily, concentrating on an area about the size of an human thumb. Though this is a fairly standard technique in the woodworking industry, the shine and gloss of the surface finish is dependant on the skills of the craftsman.

<Processing Method of the [Jidaiyaki Finish]>

  1. The wood's surface is charred using a blow torch, carbonizing it. (Due to paulownia having low thermal conductivity it is difficult to heat, it is common for house fires to occur but for paulownia drawers to remain intact) 
  2. A brass wire brush is used to remove the char created by the blowtorch. 
  3. Wood filler powder is rubbed into the surface of the wood. 
  4. Special wax for paulownia is rubbed into the surface of the wood, finish it off.

<Properties of [Jidaiyaki Finish]> 

  1. The surface of the wood is resistant to scratches due to the carbonizing process.
  2. Improved insect repllent properties and ani-bacterial properties.
  3. Improved water resistance (for everyday use)
  4. Prevents discolouration due to aging, and is said to keep its colour intact for over 100 years.

■ Craftmen's Comments

At our company, we only use wood from paulownia trees that we have carefully grown in Niigata. In order to keep the wood from discolouring or deforming with age, it is common for us to weather the wood for over 10 years.

It is not possible to completely remove the impurities in the wood by industrial means. It it common for companies abroad to bleach their wood to clean the outer faces in a timely manner. However after several decades of use, it is evident that such shortcuts yield wood which discolours and warps over time.

Just like the paulownia drawers which are gifted to newly weds which last for decades, we wish for the products designed in this competition to last a life time, using the very best of our materials and woodworking techniques. We are very much looking forward to receiving lots of your product plans!

  • スパムとして報告する kurumi kurumi 基本的には、箱物になるデザインと考えてますが、ふたに模様を描くとき、レイザーなどのイメージで焼き付けるなどして提案もありなのでしょうか?
    スパムとして報告する TRINUS TRINUS ご回答が遅くなり大変申し訳ありません。
    ご質問ありがとうございます。
    レーザーで焼き付ける加工自体は、外部委託する形になりますが可能です。
    ただ、加工できるサイズに限度があり、30cm×60cmの範囲となります。
  • スパムとして報告する 大湊 陽輔 大湊 陽輔 私は新潟で木工の工場を営んでいます。私の街は桐箪笥が有名でしたが、生活様式の変化で廃れてしまいました。桐という難しい素材の特性を活かした箪笥の加工技術を利用して「ワインや日本酒を持ち運ぶトランク」を作ってドイツで発表しました。しかし弊社は作る事は得意では有りません。同じモノをそちらで造ったら素晴らしいモノが出来ると思います。
