Properties

Rio Rosewood numbers amongst the most beautiful and most expressive woods on this earth. Its irregular marking (ears) and its variegated streaks result in highly decorative and most beautiful architectural woodwork. Brazil has banned the export of logs since 1968.

Machining

Despite its extreme hardness Rio Rosewood can be easily and cleanly worked with all tools. Planing and molding produce very smooth surfaces.

Seasoning

Drying is easy and without any great risk of checking and warping. Only a little end checking can occur.

Finishing

All surface treatments are possible. Oily content of pores can make high polishing difficult.

Jointing

Rio Rosewood can be easily glued and the joints are highly durable. Nail and screw joints hold firmly but should be pre-drilled.
