Mongoy

Scientific name: Guibourtia ehie J. Leonard

Geographic origin: West Africa and Central Africa

Description

  • Sapwood: Yellowish white colour that darkens with the light effects and changes into grey.
  • Heartwood: greyish brown with frequent dark grey shades.
  • Fiber: Straight. Slightly intertwined fibers are very frequent.
  • Grain: Thin.
  • Defects: white deposit bags

Capacity of being impregnated

  • Sapwood: Capable of being impregnated
  • Heartwood: Low capacity of being impregnated

Mechanization

  • Sawing process: ordinary difficulties arise from hardness.
  • Drying process: Medium speed to low speed. Little risk of deformation and crack formation.
  • Planing process: Appart from hadness difficulties, risk of repelling is very frequent due to the intertwined fibers.
  • Gluing process: No difficulties.
  • Nailing and screwing process: Pre-drilling is required
  • Finish: No difficulties

Observations

They usually are small diameter trunks and so it is difficult to obtain wide Goods.
Its streaking can be black or can have a strong pattern deppending on its origin
