Description
A cream-color wood obtained from the Gmelina arborea tree native to India. Gmelina wood has a medium texture with a straight or roey grain. It is easy to work and polishes to a silky smooth finish with a high gloss. Gmelina wood is used for furniture, cabinetry, boatbuilding, musical instruments, and decorative boxes. The tree is also cultivated for papermaking pulp.
