The technique to make such paper is quite special
First the crafts people clean the roots and then peel them into three parts - the bark, the inner bark and the soft wooden core.
All three are raw materials but the inner bark, which has special resilience, is the one that makes the special Tibetan paper valuable to Buddhist scriptures.
Workers then tear the inner bark into small pieces by hand and mix some alkali to make the pulp, which serves to whiten the paper.
After several times pulping and heating to refine the mixture, the pulp is ready.
The pulp is placed into the mould and dried in the sunshine, completing the process. The traditional Tibetan paper-making technique flourished as monasteries across the region published numerous Buddhist scriptures.
