What Is Yellowheart?

Yellowheart (Euxylophora paraensis), sometimes called Pau Amarello, is a tropical hardwood native to the rainforests of Brazil. It is renowned for its naturally bright lemon yellow colour.

Dense yet easy to work, Yellowheart is an excellent choice for both decorative inlays and functional projects, offering a combination of visual appeal and dependable performance that few exotic species can match.


Yellowheart Appearance and Colour

Yellowheart’s defining feature is its radiant colour and uniform, satiny texture. When freshly cut, it is bright and almost glowing, gradually maturing into a rich golden tone.

Typical Characteristics:

  • Heartwood: Brilliant yellow to golden yellow, darkening slightly to amber with age.
  • Sapwood: Nearly indistinguishable from heartwood with uniform tone.
  • Grain: Generally straight, sometimes slightly wavy.
  • Texture: Fine and smooth with a natural satin feel.
  • Luster: Excellent, finishes to a glassy sheen.

Yellowheart is often used in designs where colour and light interaction are key elements.


Working Properties and Hardness

Despite its density, Yellowheart machines cleanly and predictably. It offers smooth results straight off the tools and behaves similarly to premium domestic hardwoods.

Technical Overview:

  • Janka Hardness: Approximately 1790 lbf, similar to Hickory
  • Density: Moderately heavy and strong.
  • Workability: Excellent, planes and sands easily.
  • Gluing and Screwing: Very good with standard adhesives.
  • Finishing: Excellent, requires minimal effort for a polished look.

Yellowheart offers the workability of a domestic hardwood with the visual impact of an exotic.
