I am assuming that this melting process is taking place in room temperature, or at any constant temperature from a heat source.
There are 3 ways in which you can do this:
1. Using the concept of pressure
2. Decreasing the exposed surface area of the ice to the heat source/environment.
3. A combination of 1 & 2
4. Use a preservative(salt)
1. Using the concept of pressure (This concept is also used in refrigerators)
When applying pressure(force per unit area) to the ice, the solid particles need a longer time to attain the large amount of heat energy they need to break the forces of attraction between them against the pressure applied. This directly slows down the rate of the ice's melting.
You can apply this pressure using a compression pump. You may want to search for other methods of applying pressure on the internet as well.
2. Decreasing the exposed surface area of the ice to the heat source/environment.
When lesser surface area of the ice is exposed to the heat source/environment, the rate of heat gain by the ice is greatly slowed down, as the ice has limited places to absorb heat energy from to change state.
3. A combination of 1 & 2.
Instead of getting a compression pump, you may as well take a solid and strong material(e.g. a metal case) that fits around the ice almost perfectly, except for being opened at its top surface, place the ice in it and connect it to the heat source/environment.
This way, while the ice particles are fighting to overcome the pressure by the solid casing around it, it takes a longer time to receive heat energy from the heat source/environment simultaneously.
You could freeze the ice together with the solid casing before doing this to make sure that the ice fits in it just right
4. Use a preservative(salt)
Apply salt or any other preservative to the ice and it would take a longer time to melt.
I hope I have managed to answer your question. Do give me feedback if this is not what you wanted.
There is no ice cube that never melts under normal conditions. However, there are materials like Pykrete, which is a mixture of sawdust and ice, that melt at a slower rate compared to regular ice cubes.
To make prosecco ice cubes for summer cocktails, simply pour prosecco into an ice cube tray and freeze until solid. Add the prosecco ice cubes to your favorite cocktails for a refreshing and bubbly twist. Enjoy!
in a block of ice the ice is packed more closely together causing it to melt slower. Just like when you make a snowman, even after all the snow on the ground has melted the snowman still remains.
To make ice cubes using boiled water, simply boil the water first and then let it cool down to room temperature. Pour the cooled boiled water into an ice cube tray and place it in the freezer until the water freezes into ice cubes.
To make globe ice cubes for a unique touch to your drinks, use round ice molds or balloons filled with water. Freeze them until solid, then carefully remove the ice from the mold or balloon. Place the globe ice cubes in your drinks for a visually appealing and eye-catching addition.
Definetely! Bigger cubes melt slower.

Water :)
a ice cube melts when it heats up
Ice melts slower
Adding sugar to water before freezing it to make ice cubes can actually make them melt faster. The sugar lowers the freezing point of water, causing the ice cubes to form at a higher temperature. This means that they will melt more quickly when added to a drink.
Square ice cubes, octagon ice cubes, and hexagon ice cubes will melt at the same rate, assuming they are all the same size and made of the same material. The shape of the ice cube does not significantly impact the rate at which it melts.
Sugar has very little effect on melting point - it is too high molecular weight. That might answer your question, which does not make sense as written. Thus, it melts faster with sugar, because other ice cubes slow melting.
Salt melts ice cubes.
It melts faster alone because the others are not cooling it off.
It melts slowly.
salt melts ice because it wants it to die
