The Dyeing of Buri Straw.
Buri straw intended for mats is usually colored with the cheap imported coal tar dyes previously noted. It is expected that the new dyes for which the Bureau of Education has arranged will take the place of these. Romblon buri mats, which are the finest in point of workmanship and design made in the Philippines, are colored entirely by local vegetable dyes.
The methods used in the island of Romblon in dyeing buri straw have been carefully investigated by Mr. Barron, and are presented herewith. In each case the unit of material is one stalk of buri for each color. The process of whitening Romblon buri straw has already been described.
For red, unopened leaves having stems three feet long should be selected. The midribs are removed while green, and the leaves are rolled into bundles of convenient size, say by fives. These are boiled in clear water for about three hours, after which the segments are spread in the sun for three days to dry. Care should be taken that they are not exposed to rain or dew. They are then placed in a fluid made by boiling two gantas of kolis leaves (see mordants) in plain water for one hour. The buri leaves remain in the water and soak thus for three days and three nights. The buri leaflets are then placed in a vessel containing two gantas of sappan wood (see dyes), one-half liter of lime water, and one chupa of tobacco leaves. To this a sufficient quantity of plain water is added to thoroughly submerge the buri, and the whole is boiled for eight hours, being stirred at short intervals to obtain a uniform shade of red. The segments are then removed and hung in the wind for about six hours to dry, after which they are smoothed and rolled.
For yellow-orange, unopened leaves having stems about two inches long are selected and the segments are removed from the midribs and rolled into bundles. These are boiled in clear water for about three hours and spread in the sun for three days to dry, care being taken that the buri is not exposed to rain or dew. The material is then placed in a vessel containing one ganta of powdered turmeric (see dyes), one chupa of powdered annatto seeds (see dyes), one liter of lime water, and sufficient clear water to cover the buri, and is boiled in this mixture for five hours, with frequent stirring. It is then removed and hung in the wind for one-half day to dry, and is smoothed and rolled.
For green, an unopened leaf having a stem about two inches in length is selected. The segments are removed from the midribs, rolled into bundles and boiled in clear water for about three hours. After this, they are boiled in lye (consisting of ashes) for about two hours, the mixture of ashes and water covering the buri during the process. The bundles are then removed from the vessel, wrapped in a bayon, and put in a dark place for 48 hours. The segments are then taken out and hung in the wind for about three hours to dry, and are smoothed and rolled.
The preliminary steps in the production of “black straw” (a cold dark gray) are the same in the making of the green material. The segments taken from the bayon, as described above, are buried three days in black mud, in a rice paddy, for instance. The material is then washed in plain water until clean, and is then boiled for two hours in a mixture of one-half ganta each of the leaves of talisay, indigo, and tiagkot (see dyes), with a sufficient quantity of water to cover the mixture. The whole should be stirred at frequent intervals. After two hours the strips are removed and hung in the wind for five hours to dry. Then they are smoothed and rolled.
Types of Buri Mats.
The Bontoc Peninsula of Tayabas produces great quantities of baling mats and bayons. Bayons are also produced in large quantities in Capiz province. Other localities are of less importance.
