Control of Oleo-resin deposition in Deodar wood containers

ABSTRACT
Intro: Deodar (Cedrus deodara) is one of the most important softwood species of Pakistan. It is extensively used on account of its properties e.g., lighter weight, straight grain, good seasoning and working characteristics and high durability. One of its important uses is the manufacture of containers for various items. However, tarnishing of the metal surface of the material kept in
deodar containers is generally observed. This difficulty arises due to the presence of oleo-resins in the wood which are volatile at room temperatures and to which it also owes its characteristics odour and durability. The wood is reported to contain 2.5% of oil (1). Once deposited on the metal surface, the oleo-resins of deodar being sticky, are difficult to remove. Therefore, a study was undertaken in the
Forest Products Research Division of the Pakistan Forest Institute, Peshawar, to determine the effectiveness of aluminium paint in protecting the contents of deodar containers from deposition of oleo-resins.
