Grading of Agar Wood

Usually just before the start of manufacturing process a primary classification is made. Final classification is made after the processing has finished. In some cases Agar wood is so classified that it never needs a second or final classification, even after being manufactured. Workman brings shape and gloss to the pieces with their indigenous tool-knives, chisels, hacksaw blades etc. They exert them best skill to give the product a graceful finds.
Manufactured Agar wood is roughly grouped into four categories Viz grade I, II, III & IV. Black and solid pieces come under grade-1 while black and semi solid ones make the grade II. The third one comprises the tan colored pieces which are solid semi-solid or hollow. Agar of dark black color having natural small holes and are of relating light weight fall under the third grad as well the next is the fourth grade which generally does not hold any commercial value or prospect for a customer, Agar oil (locally named attar) which is in constant demand in the market.
When classifying Agar wood during its crude or raw condition, these four categories are expressed by the local term as Agar, Bota Doom, & Ghatia respectively. There is another kind of Agar wood harvested form an Agar wood tree which is shell- like and usually does not have any knots, nodes or swells in its tissue or texture this is called Kalagachi in local term. The Kalagachi kind is chopped geometrically shapes, these are classified accordingly as the quality or colour range mentioned above. It is seldom hollow or borous. This kind of Agar wood is in high demand but it is scarcely available and its supply is few and far between.
