I spent yesterday morning sawing small blocks of Brazilian tulipwood and African blackwood into thin slices. Tulipwood is "bois de rose" in French, which seems more appropriate since the wood does have the variety of pink hues you find more in roses than tulips. However the English name "rosewood" is used for other species of the genus "dalbergia". At any rate, Brazilian rosewood is a very dense and strong wood, highly figured and colored, jewel-like really, so a little bit will go a long way. African blackwood is also a member of the dalbergia genus, also terrifically dense and hard, black with dark brown veins. So I've built up a small reserve for bridges, saddles, nuts and inlays.
You never know exactly what you'll discover when slicing a piece of figured wood and it's always exciting to bring those hidden treasures to light.
