Wood, being a natural material, tends to exhibit slight differences in shape, size and finishing. Unlike the engineered varieties, logs are marked by their unique visual characteristics, such as spiral grains, dead knots, green knots, twist in wood, textures and colours, which naturally make their way into the finished product also. During processing of wood, at times the knot may be removed completely and at other times, it may get distributed randomly throughout the piece.
In factories, the pieces undergo multiple processes like sawing, drying, machining, jointing, glueing and so on. However, products require human intervention at many levels before they can be certified “fit for shipping”.
