Method for make leaf bookmark

1. Material preparation: leaves, wok, sodium carbonate, calcium carbonate, sodium hydroxide, tweezers and bleaching powder, brushes, etc.

2. The specific steps of making leaf bookmarks:

(1) Put some water, about 200ml, in the wok, then put 5g of calcium carbonate and 7g of sodium hydroxide in the wok and heat it.

(2) Choose leaves with clear veins and fleshy mesophyll to cheat out, put them into the just-prepared alkaline water to boil, and pay attention to the temperature.

(3) After cooking for about ten minutes, the color of the leaves gradually changes color. Use tweezers to gently swing the leaves in the water, so that the leaves can corrode the whole body evenly, and then turn off the heat until the leaves are all discolored.

(4) Pick up the leaves with tweezers and put them on the table to dry, then gently brush the leaves with a brush to brush off all the remaining mesophyll, leaving only the veins of the leaves.

⑤ Prepare a water cup or a small basin, add 40ml of clean water and 8g of bleaching powder, stir well and evenly, then add 6g of potassium carbonate into 30ml of boiling water, and after the two liquids are mixed evenly, add 100ml of clean water. The prepared liquid is bleaching liquid, and the leaves are put in for bleaching. The leaves are very transparent after bleaching, and then they can be colored with pigments. Put the leaves in the paint and soak them for a long time. Finally, take out the leaves and dry them, and the bookmark of the leaves is ready.

How to make vein bookmarks:

Veins bookmarks is made of veins only by removing epidermis and mesophyll tissue. On the bookmark, you can see that a thick vein in the middle is called the main vein, and many smaller branches on the main vein are called lateral veins; On the lateral vein, there are smaller branches called veinlets. In this way, the whole venous system is finally connected into a network structure. Dye the mesh in various colors, tie a ribbon and make a beautiful mesh bookmark.

Materials required:

1. Leaves. Generally evergreen woody plants are better. Such as osmanthus leaves, heather leaves, papaya leaves, eucalyptus leaves, tea leaves, magnolia leaves and so on. 2. Sodium hydroxide. 3. Anhydrous sodium carbonate. 4. beaker. 5. Iron shelf. 6. Alcohol lamp. 7. Soft-haired old toothbrush. 8. Glass plate (intravenous brush pad)

The leaves selected as bookmarks should meet two requirements: 1, and the veins are reticulate. Needle-like leaves such as transverse veins and pine needles in ginkgo orchards are not desirable. 2. The veins are clear and complete, which ensures that the veins will not be corroded together with mesophyll, and also reduces the incidence of veins being brushed off when mesophyll is removed.

Production method:

First, the rapid production method

1. Select the blade. Choose leaves with thick veins. Choose leaves in late summer or autumn when they are fully mature and begin to age.

2. Boil the leaves with 10% sodium hydroxide solution. Boil the prepared lye in a stainless steel pot or an iron pot, then add a proper amount of washed leaves and boil. At this time, gently rotate the blades with a glass rod or tweezers to prevent the blades from overlapping and make them evenly heated. Open the window for ventilation, because there is a bad smell when boiling leaves. )

3. Cook for about 5 minutes. After the leaves turn black, take a leaf and put it in a plastic basin filled with clear water. Wash it carefully with clear water. (Note: In this operation, leaves should not be taken and placed directly by hand to prevent sodium hydroxide from corroding hands. Take and place with tweezers or clips. )

4. When the residual lye on the leaves is washed clean, take it out, lay the leaves flat on a piece of glass, gently brush off the rotten mesophyll on both sides of the leaves along the vein direction with a small tube brush or a soft-haired old toothbrush, and rinse with small-flow tap water while brushing until only veins are left.

5. Soak the vein in hydrogen peroxide for 24 hours to achieve bleaching effect.

6. Brush the pulse sheet, rinse it off and put it on the glass sheet to dry. Air-dried to a semi-dry and semi-wet state, coated with all kinds of dyes, and then sandwiched in old books and newspapers, and then taken out after absorbing moisture, it can be used as veins bookmarks. After drying, dye it in your favorite color with red and blue ink or other dyes, and then tie a colored ribbon on the petiole to make a context bookmark with clear context, colorful, beautiful and practical.

Second, the bubble method

If the above drugs or props are not available, you can use the simplest bubble method. The method is very simple, that is, soak the leaves in water for a week or two to let them rot naturally, and then brush the mesophyll along the veins with an abandoned toothbrush to make a beautiful veins bookmarks. If you want to speed up, you can add some alkaline bath products to the water (it seems that it is necessary to maintain a suitable temperature during the soaking process so that bacteria can multiply. Try to avoid hot weather. Anyway, it was too hot to make it. )。 Dyeing the finished veins bookmarks and taking it to the photo studio for molding will also make the bookmark more beautiful, and it is also suitable for being used as a bookmark and more suitable for giving to friends and relatives. Although the gift is small, it is also very popular.
