'''''Quebracho blanco''''' ([[syn.]] ''Macaglia quebracho-blanco'' ([[Schltdl.]]) [[A.Lyons]]) is a [[South America]]n [[tree]] [[species]], which is found in the northern regions of [[Argentina]]. It must not be confused with other species also known as ''[[quebracho]]'', but belonging to the [[genus]] ''[[Schinopsis]]''.

Quebracho blanco wood is uniformly yellow-ochre, without differences between [[hardwood]] and [[sapwood]]. It is quite heavy ([[relative density]] = 0.885 [[gramme|g]]/[[cubic centimetre|cm³]]) and hard, and responds well to bending and shock. Upon drying it tends to collapse, producing deformations and cracks, so the drying process is slow; the wood must be treated with [[fungicide]]s. It is easy to work and has many uses in [[carpentry]] (carts, wheels, floors, shoes, tool handles, furniture); it is also good for [[chess]] pieces, [[ski]]s, etc. Preserved with [[creosote]] it can be used outdoors. In some places it is widely used as [[coal]], since it does not produce sparks or large amounts of ash, and it burns strong and slowly.
