    An autumn wind blows, and the golden leaves dance like butterflies. My mother and I picked out some osmanthus leaves, maple leaves, bamboo leaves, and ginkgo biloba leaves in the garden to make leaf vein bookmarks and treasure autumn forever in my books.

    I prepared an iron pot, alcohol, and red ink. First pour half a pot of water into the pot, wait for the water to boil, put the alcohol and leaves into the pot and boil, boil for 30 minutes, I found that the maple leaves, bamboo leaves, ginkgo biloba leaves are rotten, only the osmanthus leaves are still not moving. Why is that?

    A big question mark rose in my head.

    My mother checked, and it turned out that the leaves with thick flesh were not easy to burn, and strong alkali should be used. But there is no strong alkali at home, what should I do? I was very disappointed. Mom had an idea and came up with a good idea to replace it with edible alkali. I was filled with confidence again.

    The second experiment began, and I couldn't wait to put a lot of edible alkali and leaves in the pot and boil it. In a few moments, the leaves were tumbling in the boiling water, and my heart was going up and down with the leaves. Minutes and seconds passed, and after two or three hours of burning, the water slowly turned green and red, and the leaves turned black.

    Then I used my chopsticks to remove the leaves from the pot and tried to brush off the mesophyll with a toothbrush, but the mesophyll did not come off and the pot became shiny. My mom and I laughed, what was going on? Mom called the science teacher, and the science teacher said that there were two reasons:

    One is because the strength of edible alkali is not enough to remove the mesophyll, and the other is because the alkali and iron have a chemical reaction, so the pot is so shiny! It turns out that there is a lot of knowledge in this!

    After boiling the water to about 80 degrees, put the leaves in it, boil until the mesophyll turns yellow, and then continue to soak until the water temperature drops to about 40 degrees, and remove the mesophyll with your fingers or a soft toothbrush. After the final design is completed, it can be taken to the photo studio plastic package. It's okay without alcohol.

    You can choose leaves with thick veins, fine veins, and thick mesophyll for later use. Use a beaker to hold 200ml of water, put 5g of sodium carbonate and 7g of sodium hydroxide in the water, and heat it on the fire. After boiling, put the leaves into the cup and boil for about 10min.

    In this process, the blades are gently swung with tweezers so that the blades are evenly corroded. After boiling, the leaves are clamped out, put in a glass jar filled with water, brush off the part of the leaf veins other than the leaf veins with a soft-bristled toothbrush (preferably a bristle toothbrush), expose the leaf veins, and then release the bleaching liquid to bleaching (that is, 8g of bleaching powder is dissolved in 40ml of water, and then 6g of potassium carbonate is dissolved in 30ml of boiling water, then the two liquids are mixed and shaken, and 100ml of water is added after cooling, and it becomes bleach after filtration). After bleaching, the vein specimen can be dyed in a variety of colors as needed.
