When you put the leaves in a casserole and boil them with lye, why do you use chopsticks to gently p

Prevents the blades from being stacked and heats them evenly.

Please see the following explanations: 1. Select the blades. Choose leaves with thick and dense veins.

Generally evergreen woody plants are preferred. Such as osmanthus leaves, heather leaves, papaya leaves, eucalyptus leaves, tea tree leaves, magnolia leaves, etc. Leaf selection is made in late summer or autumn when the leaves are fully ripe and begin to age.

2. Boil the leaves with lye. The configuration of lye: calculated according to 1 liter of water, 70 grams of sodium carbonate (soda), 50 grams of sodium hydroxide (sold in the above two pharmaceutical and chemical stores), lime water can also be used instead of lye, put the prepared lye solution into the appropriate amount of washed leaves after boiling in an enamel cup or sand pot, boil, and gently pluck the leaves with chopsticks to prevent the leaves from being stacked and heated evenly.

Boil for about 5 minutes, and when the leaves turn black, take a leaf and put it in a plastic basin with clean water. Check the corrosion and easy peeling of the mesophyll, if it is easy to separate, you can take out all the leaves, put them in a plastic basin filled with clean water, and then separate the mesophyll from the leaf veins one by one. Note:

Do not pick and place leaves directly by hand to prevent lye from corroding the hand surface. Pick and place with tweezers or clips.

3. Remove the mesophyll. Place the boiled leaves on the palm of your hand or on a glass plate, use the smooth handle of an old toothbrush and gently rub on the surface of the leaf to wipe off the corroded mesophyll, then rinse under the faucet and continue to rub until the mesophyll is completely removed.

4. Bleaching leaf veins. Put the brushed leaf veins in the bleach powder solution and take them out, rinse them with water and sandwich them in old books and newspapers, absorb the water and take them out, which can be used as leaf vein bookmarks.

5. Dyeing, drawing, writing. Dye it in your favorite color with red or blue ink or other dyes, or you can draw or write on it, and finally tie silk thread.

Hope it works for you!

There are several reasons for this:

1.In a strong alkaline environment, if you use NaOH, it's fine, but if you use lime water, especially if you boil it into a sticky semi-paste Ca(OH)2, this thing sticks to the leaves, which is not fun. Imagine how to win it?

2.In a strong boiling solution, if zeolite is added, this can prevent the liquid from splashing due to boiling, but if it is not added, you can use chopsticks to stir or pluck to prevent boiling.

I hope it will be helpful to you!

Prevents the blades from being stacked and heats them evenly. Boil for about 5 minutes, and when the leaves turn black, remove one leaf.

and place in a plastic basin with clean water. Check the mesophyll for corrosion and easy peeling, if it is easy to separate.

All the leaves are fished out and placed in a plastic basin filled with water, and then the mesophyll and veins are separated one by one.

The problem is very simple: the purpose of holding chopsticks is either to be afraid of hurting your hands, because the lye is reduced when it hits the boiling water.

The corrosive temperature is very high, and the second possibility is not ruled out that the leaves are afraid of sticking to the bottom, so as not to touch the liquid during the production process, so as not to roll out the body fluids...

Allow the liquid to contact the ...... evenlyBe careful and do not have anyone nearby.

This makes the bookmark more beautiful.

It can heat the blades evenly.

Good compatriot, I am also a junior high school student, and I am from Bowen Middle School, what about you? Unfortunately, although I am very good, I can't answer the question for you.

1.Prevents blades from sticking.

2.Prevent liquid splashing due to boiling.
