Biological Experiment – Making Wine (with illustrated plates).
Ladies and gentlemen, after a year of theoretical research, biology finally has its first experiment - making wine.
First of all, I bought grapes, according to Mingyu, white grapes are the best, but I don't know what white grapes are, so I bought a few catties of ordinary grapes.
** 6 yuan Jin (can you report **, so that it can play a control role).
First of all, I washed it, and since I couldn't break the branches, I soaked it in water and fished it out.
Pretend to wash it, but you have to wash it clean.
Then, put it in a pulverizer and beat it into an inexplicable viscous liquid. She said that the juicer was not clean, so I borrowed a grinder from the neighbor's grandfather).
Workhorse: Pulverizer.
Squeeze a piece of fruit with branches.
work. Try it first.
It's better to go to the branch.
Then, filter, preferably with gauze, but a clean laundry bag can also be filled.
Then, you have to use your hands, wash your hands, and meditate on the feet of the ancients. Start filtering. Of course, it is best to have filter paper, but not enough.
Believe: the ancients really used their feet.
After filtering, divide and pack.
I set up a control group (the left bottle) with a yeast tablet in it. If you have a lot of juice, you can also set up a control group to benefit from it.
Regarding storage: I recommend keeping it in a place that will not be exposed to direct sunlight or stuffiness.
I put my juice in another useless kitchen and set up a tripod for easy documentation.
The original juice that has been placed can be compared in the future. Please be prompt! Thank you! ~

There are many products made of ceramic raw materials on the market, including common ceramic bowls, ceramic pots and pans or some ceramic tiles, which are all new building materials and furniture appliances with reliable performance and excellent cost performance, but in the later use process, we may find that the ceramics are broken, and even affect the beauty and practicality. Today, I will give you an example of how to bond the broken ceramics and techniques.
1. How to stick the ceramic when it is broken.
Most ceramics are a kind of products, but also a kind of fragile products, if you are not careful, it is easy to break, because ceramics are clay as the main raw material and various natural minerals through crushing and mixing, molding and calcination of materials and various products. So what glue is better for ceramics to be glued, and what are the adhesive methods of ceramic glue?
Usually the more professional glue for adhesive ceramics is marble glue, which is used together with the quick-setting agent, but often we are not so professional to find this glue; Then you can also try the more common instant adhesive 101, or the more common AB glue, but the effect is not as good as marble glue! If you want the beauty of the appearance while pursuing the fastness of the bond, then choose the shadowless adhesive, which is now used for ceramic bonding, and the fastness of the shadowless adhesive used for ceramic bonding has also reached a high strength, although the ratio is a little worse than that of epoxy.
Second, the ceramic is broken and bonded.
1. Ceramic and plastic bonding. For example: JL-100 acrylic acid blue and red AB glue.
Homogeneous or heterogeneous adhesion to all kinds of metals, magnets, ceramics, stone, wood, hard PVC, FRP, etc. For the adhesion of metal objects, the impact strength is better than that of epoxy resin. Excellent heat resistance, placed at 150 for a week, and also placed at room temperature, the strength is not weak.
Vibration resistance: iron-to-iron, vibration 1000 times per minute, vibration resistance 106, irradiation under ultraviolet rays for 200 hours without decreasing intensity.
2. Other adhesives for bonding ceramics: such as: poly JL-510 high temperature resistant 200 epoxy resin AB glue, JL-611 1 hour epoxy resin AB glue, JL-610AB 10 minutes fast drying transparent AB glue and so on.
They also have excellent bond strength for encapsulation bonds between metals, ceramics, wood, glass and rigid plastics.
The relevant knowledge of ceramic pottery is introduced here, and the above also introduces some of its bonding methods in detail, you can refer to it, mainly depending on what product you are, and then determine the specific media resistance of the product after bonding, that is, the specific bonding requirements, and then we will judge how to use glue better.
Through the above, it can be known that if it is a bowl and chopsticks made of ceramic raw materials, or the pot is broken, which affects the beauty and practicality, then we can carry out a series of operations, such as choosing the right glue for connection, or seeking professional institutions for maintenance and repair, these are good suggestions, and the above is an example of the specific connection method and skills and precautions for ceramic breakage, and interested friends can operate in case of emergency.

The method of mending the crushed ceramics is as follows:
Materials required: raw lacquer, black lacquer, egg whites or glutinous rice flour, gold leaf, knives, sandpaper, pens, hair dryers, electric kilns, utility knives.
The specific steps are as follows:
1. First fix the tire with raw lacquer, coat it on the ceramic section, and bake it in the kiln.
2. Prepare glued lacquer.
3. Stir until the paint is viscous, and stir with a hair dryer while heating to accelerate the reaction.
4. The ceramic section is coated with glued lacquer.
5. Glue the pieces together.
6. The state after the bonding is completed.
7. Fill the surface gaps between the fragments.
8. After filling, carefully polish with sandpaper.
9. Apply another layer of red paint on the cracks.
10. After the lacquer is half dry, cut the gold leaf to a suitable size, and then paste the gold leaf on the lacquer.
In this way, the repair of the ceramic is completed.
Notes:Be careful when using bracket knives and utility knives so as not to hurt your hands.

Hello, it's better to stick with 502, the good penetration of the two brothers is relatively poor, or it is easy to break and there will be a certain gap in the middle. A wash the ceramic pieces and dry them without too much dust, b use 502 to bond them in the crushing out, and quickly glue them (dry relatively quickly), c After gluing, leave them for a period of time to ensure that they are completely dry.
d Mix the gypsum and water evenly for use (note: pour a certain amount of water into the container first, and then add the gypsum slowly, otherwise it is easy to produce bubbles, the ratio is basically 1:1, put it for half a minute to let the air in the gypsum run out and then stir it quickly).
When the gypsum is paste-like, the adjusted gypsum is picked on the damaged part with a hacksaw blade, and the plaster is carefully patched, paying attention to making up more than the original type, so as to facilitate the next operation.
f Leave the repaired model for 5 minutes, and when the surface of the plaster is hot, hang off the higher part of the plaster with the sawtooth surface of the hacksaw blade, and then dimmer it with sandpaper and polish it smooth together with the traces left by 502.
g Place the repaired porcelain in a cool, dry place for 4 to 5 days until the plaster is completely dry.
h First mix acrylic paint into a color similar to the glaze and apply it to the plaster surface until the acrylic is completely dry. Great success.
In addition to applying acrylic paint, the above steps are the repair steps of cultural relics, in fact, not to draw acrylic is also very good-looking, there is a sense of vicissitudes, very temperamental, you might as well give it a try.

It's sticky with the brothers, and you can buy it in a general hardware store. However, if there are no fragments, use plaster powder to repair them, and after repairing them according to the original shape, you can apply a color similar to the original work. Use color to make some artistic effects on it.
If you have other questions about pottery, you can go to QQ to find Tao Ran Juyi.
