Many people have tried a lot of ways to make the ice last for a long time, but we can take the following measures, which will be very effective
1. Make large ice cubes: Before making ice, boil the water. Bring the water to a boil in a kettle and let it cool enough to fit in a plastic tray. In doing so, the air in the water is removed, making the water denser. The larger and denser the ice cube, the longer it will take to melt. An added benefit is that it makes the ice more translucent.
2. Preserve ice cubes correctly: Use insulated ice buckets. Ice buckets made of styrofoam or insulated plastic can keep the ice for about 15 to 2 hours without melting. Use ice buckets that drain water. Ice soaked in water melts quickly, so draining it regularly will keep the ice longer. Cover the inside of the ice bucket with aluminum foil. Doing so will keep the temperature of the ice cubes. Cover the ice bucket with a lid or board to maintain the temperature inside the bucket. Hot air will make the ice melt faster. Keep away from sunlight and hot food containers. It's best to set the wine table in the coolest place.
3. Add salt: Before making ice, to the boiling water, press "6 grams of salt ratio 3."5 liters of water" in the ratio of salt. Salt raises the melting point of the ice, so that the ice melts slowly. An hour before the party starts, take out the salted ice cubes and thaw them. Salted ice cubes can be used to mix cocktails with a salt edge, such as a margarita, a Bloody Mary or a Michelada.
4. Stainless steel ice cubes: Ice cubes made of 316 stainless steel are used, which can be used repeatedly. In the summer, add it to a drink or wine and it can be quickly chilled.
