A specis of dry highland forest, sometimes also cerrado, occurring on both poor and fertile soils. Heartwood Color Brown Yellow Orange Green/grey Red Black Purple The heartwood is similar to Brazilian rosewood (Dalbergia nigra ), except that it has a lighter color that is between pink brown and violet brown Sapwood Color White Yellow Grain Even Straight Straight The grain is described as undulating and is less figured than Brazilian rosewood Texture Medium Coarse Even or uniform Coarse Fibrous/Texture is coarse, and the wood tends to be fibrous Luster Medium High Natural Durability Susceptible to insect attack Non-resistant to termites Non-durable Non-resistant to powder post beetles Perishable Non-resistant to marine borers The heartwood is very resistant to attack by decay fungi Odor No specific smell or taste Drying Defects Distortion Splitting Collapse Internal Honeycombing Possible Prone to checking Ease of Drying Fairly Easy Rapidly Slowly Reconditioning Treatement Air dries slowly Kiln Drying Rate Naturally dries quickly Naturally dries at a moderate speed Drying rate is fairly rapid to fast Rapid Tree Size Tree height is 20-30 m Tree height is 30-40 m Bole length is 10-20 m Trunk diameter is 100-150 cm Sapwood width is 5-10 cm Tree height is 40-50 m Tree height is 10-20 m Bole length is 20-30 m Sapwood width is 0-5 cm Trunk diameter is 150-200 cm The tree is of medium size, and is seldom large Blunting Effect Little Dulling of cutting edges is rather severe Boring Fairly difficult to very difficult Fairly easy to very easy Carving Fair to Good Results Fairly Easy to Very Easy Cutting Resistance Easy to saw Gluing Fairly Easy to Very Easy Fair to Good Results Mortising Fairly Easy to Very Easy Very Good to Excellent Results Fairly Difficult to Very Difficult Fair to Good Results Moulding Fair to Good Results Fairly Easy to Very Easy Very Good to Excellent Results Fairly Difficult to Very Difficult Quartersawn material is reported to mold better with sharp tools and a reduced cutting angle of 20 degrees Movement in Service Excellent Stability - Small Movement Fair to Good Stability - Medium Movement Nailing Fairly Easy to Very Easy Fair to Good Results Planing Fair to Good Results Fairly Difficult to Very Difficult Fairly Easy to Very Easy Very Good to Excellent Results Jacaranda pardo is rather difficult to work with ordinary tools.
