採集構樹皮 collecting paper mulberry tree
Win Lin Yang invited us to her house to collect paper mulberry tree. We cut off a piece of tree trunk, make a cut on its skin then the tree skin can be peel off easily. Place the skin on a stone or flat surface, make it into fabric/paper form by keep knocking it to extend the fibre length. Wash the surface from time to time to wash away the black part from the oxidation. However because of the limited time, we use the pre-processed paper mulberry pulp to make the hand sheet paper.
手抄紙步驟 hand sheet papermaking steps
Soak the 600 grams of dry paper mulberry pulp into the water over night.
Fill up the water in the pulper tank, and put the wet pulp into water and start the machine. The pulps keep being cycling in the water flow and beaten by the turning spiral rotor.
After 20 minutes we make the water gate smaller so the rotor beat the fibre into smaller fibre and we beat the fibre for 10 to 15 minutes more. Finally we collect the fibre at the bottom of the machine with filter or laundry bag.
4. 將塑膠淺盆裝滿水約5分滿，再加入樹糊粉，台灣的樹糊粉萃取自馬拉巴栗樹根（俗稱發財樹或美國花生）的汁液，作為造紙的助料 - 樹糊，樹糊加入水中，可幫助紙漿纖維均勻懸浮不易沉澱，造紙厚薄均勻。有些國家也有使用秋葵或蘆薈做樹糊。樹糊是造紙的助料，又稱做『懸浮劑』或『紙藥』。在調漿過程中，加入“紙藥”，使纖維在水中均勻懸浮，使抄出的紙張纖維分佈均勻，厚薄一致。它與利用植物膠有相同的化學成分，沒有毒性，用量極少，摸起來滑而不黏，聞起來沒有味道，將會漸進蒸發，沒有污染問題。然後將抄紙網放入水中將懸浮的紙漿平均固定於網上。
Malabar chestnut tree, commonly known as the "rich tree" or "American peanut". The sap extracted from the roots of the Malabar chestnut tree in Taiwan is used as an auxiliary material for papermaking-tree paste. The tree paste is added to water to help the pulp fibers to suspend evenly and not easily settle, and the thickness of the paper is even. Some countries also use okra or aloe to make tree paste. Tree paste is an auxiliary material for papermaking, also known as "suspending agent" or "paper medicine". In the pulping process, "paper medicine" is added to suspend the fibers evenly in the water, so that the paper fibers are distributed uniformly and the thickness is uniform. It has the same chemical composition as the use of vegetable glue, is non-toxic, uses very little amount, is slippery to the touch and not sticky, smells no taste, and will gradually evaporate without pollution problems.

Then we can put the paper making net into the water and collect the pulp, let the pulp forms the shape on top of the net.
After the wet pulp form a satisfying shape on the paper making net, we take the net out of water, put it upside down and cover it on top of the absorbent paper. Then absorb the extra water from the backside with sponge. When the paper gets dry enough, you can remove the net and leave the formed paper on the absorbent paper. Leave it there for completely dry. You may accelerate this process with iron.
可實驗項目，例如 parameters to play around:
1. 抄紙的動作形成的效果 the hand movement lead different results
2. 加入的材料形成的質感 innovate different textures by adding different materials during the hand sheet papermaking process
3. 染色(先染，後染) dyeing (apply dyeing before and after)
4. 厚薄 the thickness control
5. 後處理，表面塗層 after processing, surface coating
6. 水溫，打漿時間等步驟的調整 adjust water temperature, paper pulp beating duration
混合其他材料於手抄紙 mixing materials with paper pulp and tests
activated charcoal paper pulp = 3 - 8 k ohm-cm, carbon black paper pulp = 50 - 300 ohm-cm, the range comes from the uneven thickness.
The carbon black and activated charcoal causes the loosing structure, there should be another two pulp layers to sandwitch the carbon pulp layer in between to tighten the structure. Yet we haven't test it out.
