Overview
Klinki Pine is a timber from New Guinea, usually seen only as plywood in Australia. The wood is virtually identical to Hoop Pine, but with a lower density. Like Hoop Pine, the heartwood is a straw to pale brown colour, and the sapwood is not easily distinguishable. The texture is very fine and even, and the grain is straight. Klinki Pine can be distinguished from Hoop Pine by applying a few drops of concentrated hydrochloric acid, which gives the wood an intense green colour. The plywood is used for battery separators, ice-cream spoons and furniture joinery.
