Jin

A jin is a piece of deadwood on a bonsai, usually a branch stub or trunk tip, that has had its bark removed and been shaped and bleached to look like wood weathered by wind and sun. Jin is one of the signature deadwood techniques borrowed from junipers and pines growing in harsh mountain conditions, where dead branches persist for decades.

Creating a jin starts with selecting a branch that does not serve the living design, then stripping the bark with pliers and a knife while the wood is still fresh and pliable. The exposed wood is shaped, sometimes split into strands for a more natural look, then treated with lime sulfur to bleach it and slow decay, which also gives it the pale, weathered color associated with old deadwood.

Jin pliers are worth owning specifically for this job, since regular pliers tend to crush the bark instead of peeling it cleanly. A common mistake is making a jin too thick or too straight, which reads as artificial. Looking at how jin forms naturally on old junipers helps before committing a knife to a branch that cannot be undone.
