Pine, Klinki

Home » Wood Species » Pine, Klinki

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.

Appearance

Klinki pine is very similar to hoop pine, and can be identified by applying a few drops of hydrochloric acid, which turns the wood an intense green. The texture is very fine and even, and the grain is straight. The sapwood and heartwood are not readily distinguishable, with both being a straw to pale brown colour.

Common Applications
