Heartwood Color Black Light colored sapwood Color varies considerably Black with light colored bands Color is variable. Can be black with light bands and pale zones, or with obvious contrast between whitish and black wood. Black heartwod more brittle than lighter sapwood Sapwood Color Yellow White White to yellow Variable color Reddish Clearly differentiated from the heartwood Brown Grain Even Figure Straight Irregular Irregular Generally straight, but not always Texture Fine Even or uniform Uniform Fine Even textured Natural Durability Very durable Durable Resistant to termites Moderately resistant to attack by termites Heartwood has high natural resistance to decay Wood from Sri Lanka and India is moderately resistant to attack by termites. Black heartwood has high natural resistance to decay Odor No specific smell or taste Kiln Schedules T3 - C2 (4/4); T3 - C1 (8/4) US Schedule C United Kingdom/T3 - C2 (4/4); T3 - C1 (8/4) US Schedule C United Kingdom Drying Defects Checking Black portions prone to checking during drying Standing Diospyros trees are often girdled and allowed to season before felling Ease of Drying Moderately Difficult to Difficult Difficult The timber is difficult to season, especially darker colored material Tree Size Bole length is 0-10 m Tree height is 10-20 m Tree size varies with species Blunting Effect High to severe Severe blunting effect on cutting surfaces Boring Fairly difficult to very difficult Carving Fairly Difficult to Very Difficult Cutting Resistance Easy to saw Satisfactory sawing properties Gluing Fairly Easy to Very Easy Fair to Good Results Easy to glue Mortising Fairly Difficult to Very Difficult Moulding Fairly Difficult to Very Difficult Nailing Pre-Boring Recommended Fairly Difficult to Very Difficult Pre-boring recommended Planing Fairly Difficult to Very Difficult Fair to Good Results Special attention required High density makes wood difficult to plane and work Difficult to plane Planing material containing irregular grain requires a reduced angle of 20 degrees. Diospyros timbers are generally very difficult to work with hand and machine tools in all woodworking operations because of their brittleness and high density. Wood tends to ride on cutters without adequate pressure.
