Timber texture
Jarana wood often has gum veins, showing a few mm wide lines on the surface.
Drying
Drying goes quickly, but must be done with care to avoid checking and deformation.
Workability
Machining of this heavy species goes relatively well. There is a slight blunting effect due to the silica content.
Screwing/nailing
Pre-drilling is recommended.
