My Baroque flutes are made in hardwood, mainly in European boxwood, but sometimes in a tropical hardwood such as ebony. Flutes in boxwood will be unstained if the wood is a particularly attractive piece, but otherwise stained. The keys are made in silver or brass.
My Renaissance traversos are made from boxwood, maple or olive, or from fruitwoods such as walnut and apricot.
My flutes’ white ornamental mounts, which would have been made originally in ivory, are made in bone, wood or in any natural material that is sufficiently white-coloured to distinguish it from the body of the flute. I tend to avoid use of plastics, such as so-called artificial ivory, as much as possible.
