叶脉书签的制作方法

叶脉书签就是除去表皮和叶肉组织，而只由叶脉做成。书签上可以看到中间一条较粗壮的叶脉称主脉，在主脉上分出许多较小的分支称侧脉；侧脉上又分出更细小的分支称细脉。这样一分再分，最后把整个叶脉系统联成网状结构。把这种网状叶脉染成各种颜色，系上丝带，即成漂亮的叶脉书签了。.

.一定要硬点的叶子。夏天把叶子泡水里放到太阳下晒。等水腐烂。半个月就能出叶脉。弄出来的是淡黄色的。还是上色比较好看。

其实没有那么危险，虽然是碱性水但腐蚀性并不是很大，弄到手上也没什么问题，只是不要长时间接触就行。做这种叶脉书签要树叶本身叶肉质地较软、叶脉清晰较硬之外，在刷的过程中用力均匀。一般情况下做出来几乎每一张都是有破损的。这也就是做出一个完整叶脉书签的难得之处！

材料选择与处理

1.叶子。一般以常绿木本植物为好。如桂花叶、石楠叶、木瓜叶、桉枝叶、茶树叶、玉兰叶等。

2.氢氧化叶脉书签(8张)钠。

3.无水碳酸钠。

4.烧杯。

5.铁架台。

6.酒精灯。

7.毛质柔软的旧牙刷。

8.玻璃板（刷叶脉时垫）

所选的用作书签的叶子要符合两大要求：

1、叶脉为网状脉。横向脉如银杏树叶、针形叶如松针均不可取。

2、叶脉清晰、完整，这样才能确保叶脉不会与叶肉一起被腐蚀烂，也减少去除叶肉时叶脉被刷断的发生率。

制作方法

一、快速制作方法

1.选择叶片。选择叶脉粗壮而密的树叶。在叶片充分成熟并开始老化的夏末或秋季选叶制作。

2.用10%的氢氧化钠溶液煮叶片。在不锈钢锅或铁锅内将配好的碱液煮沸后放入洗净的叶子适量，煮沸，这时常用玻棒或镊子轻轻翻动，防止叶片叠压，使其均匀受热。（应卡窗通风，因为煮叶片时有臭味）

3.煮沸5分钟左右，待叶子变黑后，捞取一片叶子，放入盛有清水的塑料盆中。小心翼翼的用清水洗净。（注意：该操作取放叶子一定不要用手直接取放，防止氢氧化钠腐蚀手面。用镊子或夹子取放。）

4.当叶片上残留碱液漂洗干净后取出，把叶片平铺在一块玻璃上，用小试管刷或毛质柔软的旧牙刷轻轻顺着叶脉的方向刷掉叶片两面已烂的叶肉，一边刷一边常用小流量的自来水冲洗，直到只留下叶脉。

5.将叶脉放入双氧水中浸泡24小时，以达到漂白效果。

6.刷净的叶脉片，漂洗后放在玻璃片上晾干。当晾到半干半湿状时涂上所需的各种染料，然后夹在旧书报纸中，吸干水分后取出，即可成为叶脉书签使用。干燥后用红、蓝墨水或其它染色剂染成你所喜爱的颜色，再在叶柄上系一根彩色丝绸带，便制得一片叶脉清晰、色质艳丽、美观实用的叶脉书签。.

二、水泡法

如果没有上述药品或者道具，可采用最简单的水泡法。方法很简单，就是将树叶用水泡上一周到两周时间，使其自然腐烂，然后用废弃的牙刷顺着叶脉的方向刷干净腐烂的叶肉，即可制成精美的叶脉书签。如果想加快速度，可在水中加入一些碱性的洗浴用品（貌似浸泡期间需保持适宜的温度，以便细菌繁殖。尽量避免炎热的天气，反正天气太热，我就没有浸泡成功过。）。将做好的叶脉书签染上颜色，再拿到相馆过塑，也会使书签变得更加精美，也适合用作书签，更适合赠给亲人朋友，礼虽小但也极招人喜爱.

Veins bookmarks is removing the epidermis and mesophyll tissue, and only made from the veins. Bookmarks can be seen on middle a brawnier said the main arteries and veins,https://www.360docs.net/doc/7016569767.html,/, veins on the main arteries and veins

gives off many of the smaller branch called lateral veins; Tell again on lateral veins more small branch said stringer. The points again, finally the whole couplet net vein system. The mesh Ye Mairan into all sorts of color, wear a ribbon, namely into beautiful veins bookmarks. .

. Must be hard point of leaves. Put leaf bubble in the water in the sun in summer. Such as water decomposition. Half a month can out of the veins. Is out of the pale yellow. Or the color more good-looking.

In fact not so dangerous, although the alkaline water is corrosive and is not very big,, there is no problem in my hands, just don't contact for a long time. Doing this kind

of veins bookmarks to mesophyll leaves itself texture is soft, clear veins hard outside, in the process of brush forcibly even. Usually makes almost every one is there is any breakage. This is to make a complete of the veins bookmarks is rare.

Material selection and processing

1. The leaves. General with evergreen woody plants, as well. Such as osmanthus leaf, heather, papaya leaf, eucalyptus leaves, tea leaves, yulan, etc.

2. Sodium hydroxide veins bookmarks (8).

3. Anhydrous sodium carbonate.

4. A beaker.

5. The hob.

6. The alcohol lamp.

7. Qualitative soft old toothbrush.

8. Glass brush Ye Maishi (pad)

The selected leaves used as a bookmark to meet two requirements:

1, the veins reticulate venation. Lateral veins such as gingko leaves, needle leaf such as pine needles are not desirable.

2, veins clear, complete, and in this way can we make sure the veins does not corrode with mesophyll and also reduce the incidence of veins was brushed off when removing mesophyll.

Production methods

A, rapid manufacturing method

1. Choose blade. Choose veins thick and dense leaves. In blade fully mature and start aging in the late summer or autumn leaves make.

2. Boil with 10% sodium hydroxide solution leaves. Within the stainless steel pan or wok will match good lye boil into the wash leaves right amount, boils, the commonly used glass rod or tweezers gently turn, prevent blade overlying, make its uniform

heat. (should be card window ventilation, because cooking blade there is bad smell)

3. Boil for 5 minutes, when the leaves turn black, make a leaf, in plastic containers filled with water. Carefully washed with clear water. (note: this operation take put

the leaves must not directly take put in hand, to prevent naoh etching ShouMian. Use tweezers or clip.)

4. When the blade on the residual alkali liquor after rinse clean, the blade flat out on

a piece of glass, with a small tube of hair brush or soft brushes off old toothbrush gently along the veins in the direction of the blade on both sides has lousy mesophyll, brush while commonly used small flow rate of tap water rinse, until leaving the veins.

5. Will the veins in the hydrogen peroxide solution soak for 24 hours, in order to achieve the effect of bleaching.

6. Clean the veins, rinse after put on the glass dry. When hanging to dry and wet state with all kinds of dye,https://www.360docs.net/doc/7016569767.html,/post/15

7.html, and then sandwiched in old newspapers, blot moisture out, can be used as veins bookmarks. Dry after dyed with red, blue ink, or other stain, your favorite color in petiole is a colorful silk ribbon, then made a clear veins, veins bookmarks color is gorgeous, beautiful and practical. .

Second, the bubble method

Without the above drugs or props, can use the most simple blister method. Method

is very simple, is to use bubble leaves on a weeks to two weeks of time, make its natural decomposition, and then use discarded toothbrush along the veins in the direction of the brush clean the rotten mesophyll, can be made into fine veins bookmarks. If you want to speed up, can in the water add some basic toiletries (seemingly soaking period to keep the appropriate temperature, so that bacteria reproduction. As far as possible to avoid the hot weather, anyway the weather is too hot, I didn't immerse successfully.) . Will do veins bookmarks with colors, pavilion to phase model, also can make bookmarks to become more elegant, also suitable for used as a bookmark, was a gift to relatives and friends, more suitable for small but also very likable guy.
