Origin of Charred Wood

Japanese Tradition

The wood charring technique, known as „Yakisugi” or „Shou Sugi Ban,” originated in Japan during the Edo period (1603–1868). Initially, merchants used this method to protect stored goods from fire damage. Later, it was discovered that this process made the wood more resistant to pests and moisture – critical in Japan, where traditional buildings were made entirely of wood and had to withstand the humid climate.

The traditional method involved binding three planks into a triangular shape and setting a fire inside. When the surface reached the desired charring level, the fire was extinguished, and the planks were used for house facades, roofs, and interior details.

Today, charred wood has gained global popularity. Modern production uses gas burners, blending ancient craftsmanship with contemporary technology. This timeless technique not only creates a unique aesthetic but also remains one of the most sustainable ways to treat wood, merging heritage with modern environmental awareness.

What’s the method behind wood charring?

01

wood

Traditionally, cedar was used for wood charring in Japan; however, it grows slowly and is not native to Lithuania, making it more expensive and harder to obtain. Instead of cedar, we char pine, larch, and spruce, which are strong, easy to work with, and naturally have beautiful textures.

02

Surface charring

Special gas torches are used for charring, and the boards are charred at a high temperature of around 1000°C. The purpose of charring is to create a charcoal surface, which acts as a natural barrier against moisture, insects, and UV rays.

03

brushing

The charred wood is fully cooled, and once the surface is cold, it is gently brushed with a nylon brush. This process removes loose carbon layers and reveals the wood’s unique texture.

04

oiling

To extend the wood’s durability even further, it is treated with oil. This process provides the desired shade, enhances the texture, and adds an extra protective layer against moisture.

Advantages of Charred Wood

What makes charred wood a great choice?

The production process of charred wood is inseparable from fire, but it is carried out under highly controlled conditions. Each board is carefully treated to create a surface layer of carbon that provides protection against moisture, insects, fungi, and ultraviolet (UV) rays. Moreover, this technology enhances the natural texture of the wood, creating unique patterns and shades.
