Arizona ironwood burl (Olneya Tesota or Palo Fierro), one of the flagship materials at Perceval, belongs to the Fabaceae family. This precious wood, which is one of the heaviest and densest in the world, is thousands of years old.
It can only be worked when it has died naturally and dried in place for some 3,000 years.
This is a naturally dark wood with very noticeable veining.
This wood is sourced in the petrified forest in Arizona, and was registered in the indicative list of World Heritage in 2008.
This site is remarkable for its concentration of fossilized tree trunks that date back over millions of years.
