Zdrojový text : Swamp Kauri 15.5.2006 - Kategorie: Kytara 35000 let a víc - tak starý je tento druh dřeva.

The Kauri tree is the oldest and tallest tree in New Zealand and can be up to 20 mt in diameter and a height of over 50 mt. It can grow to be over 3000 years old and is a protected species. Swamp kauri refers to kauri timber which has been recovered from under the ground. It comes from forests which were buried by natural cataclysmic events long ago. Carbon dating has indicated that logs were buried up to 50,000 years ago. Leaves and cones are often preserved with the logs but these quickly deteriorate when exposed to the air.

What is swamp Kauri

The term "Swamp Kauri" tends to suggest that Kauri trees grew in swamp areas. This was not the case, but rather the reverse as Kauri could not stand 'wet feet'. Over millions of years there have been great geological changes in New Zealand, involving the ice age, earthquakes, eruptions severe gales, vast floods, catastrophic landslides even continental plate movements. Forest trees were overwhelmed by the varying forces of nature. Kauri of all ages and sizes were swept from the forest hillsides ending up in the lowland swamps, eventually to be covered by river silt and subsequent landslides to remain in a state of preservation.

Kauri guitar bodies are works of art and used exclusively on Langcaster guitars. We developed a special treatment to stop the solid wood body from cracking and it is coated with layers of epoxy, then several high gloss lacquer finishes are applied creating a hard high gloss surface .

The Kauri wood we used is carbon dated and identified to be over 35000 years old. This makes your guitar unique in the world and a collectors item .

The carbon dating has been done by The University of Waikato of New Zealand and the University of Groningen Holland

For the technically minded: at 12 percent moisture content the density of kauri is 560 kg/m3; the modulus of rupture is 88 Mpa; the modulus of elasticity 9.1 Gpa. When drying from green to 12 percent moisture content tangential shrinkage is 4.1 percent and radial shrinkage is 2.3 percent.
