Note 10 — Mat Materials.

Red: In the production of red straw the bundles are treated with kolis leaves in the same manner as in the preliminary process for red-orange straw. In a pot capable of holding 25 fist bundles of sabutan, four gantas10 of finely chopped sappan are placed. Over this are placed 15 bundles of the straw, which in turn is covered with one ganta of chopped sappan. The remaining 10 bundles are then added and covered with still another ganta of sappan. The pot is filled with water and set over a fire for from twelve to fifteen hours. Care is taken that the bundles are always kept under the water and that all parts of the material are uniformly colored. The loss by evaporation is counterbalanced by adding water from time to time. When well colored, the straw is removed from the pot and placed in a large basket for a day and is then hung in the sunshine to be dried. It should be allowed to remain in the night air; when thoroughly dried it is rolled in coarse mats.
