The basic raw material is the pulp obtained from the bark of the saa tree. The bark is ground and cooked in vats to release the lignin (the substance that glues the wood fibers together). The fibers are then washed and bleached to produce a white pulp.
The pulp is mixed with water and uniformly distributed on a fine screen to form the sheet. If a special texture is desired,
the pulp is mixed with other materials such as small flowers, etc. to incorporate them in the sheet. Dyes can be added at this stage to produce colored sheets.
