<P> From the beginning of commercialization, the making of a paper brought in most of the village's population into the process in one way or another . However, in the 1980s, many men in the area began to leave as migrant workers, mostly to the United States, sending remittances home . This then became the main source of income to San Pablito, and made paper making not only secondary, but mostly done by women . The basic equipment used are stones to beat the fibers, wooden boards and pans to boil the bark . All of these come from sources outside San Pablito . The stones come from Tlaxcala . The boards come from two nearby villages of Zoyotla and Honey and the boiling pans are obtained by local hardware stores from Tulancingo . </P> <P> In the pre Hispanic period, the bark was first soaked for a day or more to soften it before it was worked . An innovation documented from at least the 20th century is to boil the bark instead, which is faster . To shorten the boiling time, ashes or lime were introduced into the water, later replaced by industrial caustic soda . With the last ingredient, the actual boiling time is between three and six hours, although with set up the process takes anywhere from half to a full day . It can only be done during certain weather conditions (dry days) and it requires constant attention . The amount boiled at one time ranges from 60 to 90 kg with 3.5 kg of caustic soda . The bark needs to be stirred constantly . After boiling, the bark is then rinsed in clean water . </P> <P> The softened fibers are kept in water until they are processed . This needs to be done as quickly as possible so that they do not rot . At this stage, chlorine bleach may be added to either lighten the paper entirely or to create a mix of shades to create a marbled effect . This step has become necessary due to the lack of naturally light bark fibers . If the paper is to be colored, strong industrial dyes are used . These can vary from purple, red, green or pink, whatever the demand is . </P> <P> Wooden boards are sized to the paper being made . They are rubbed with soap so that the fibers do not stick . The fibers are arranged on wooden boards and beaten together into a thin flat mass . The best paper is made with long fibers arranged in a grid pattern to fit the board . Lesser quality paper is made from short masses arranged more haphazardly, but still beaten to the same effect . This maceration process liberates soluble carbohydrates that are in the cavities of the cell fibers and act as a kind of glue . The Ficus tree bark contains a high quantity of this substance allowing to make for firm but flexible paper . During the process, the stones are kept moist to keep the paper from sticking to it . The finished flat mass is then usually smoothed over with rounded orange peels . If there are any gaps after the maceration process, these are usually filled in by gluing small pieces of paper . </P>
