Move the ice into a freezer.
The sawdust acts as insulation. But styrofoam or a Dewar flask will work much better.
Layers of newspaper can act as a primitive cooler if you wrap ice in them. The more newspaper, the better, but it won't keep it from melting as long as a styrofoam or plastic cooler would.
Styrofoam is a good insulator which means it slows down the transfer of heat. This insulating property helps to keep the ice from melting quickly by reducing the heat that can pass through the material. So, the ice will melt more slowly in a Styrofoam box compared to a container that doesn't have good insulation.
Objects like Styrofoam, which have low thermal conductivity and act as insulators, can slow the melting of ice by limiting the transfer of heat between the ice and its surroundings. Additionally, adding salt to ice can lower the melting point of ice, requiring more energy for it to melt, thus slowing down the melting process. Another way to slow ice melting is by using a cooler environment, such as placing the ice in a freezer or adding more ice around it to maintain a colder temperature.
i think what would preserve the ice block from melting is to try and just try different things in order to keep the ice from melting like maybe putting the ice in the deep freezer where it can stay frozen for a couple of days.
By ensuring the ambient temperature is below the melting point of the ice.
They are scattered on the iced surface to stop the ice from melting and slow down the melting.
An insulator, like styrofoam, can help prevent ice from melting by reducing the transfer of heat from the surroundings to the ice. This insulation layer slows down the melting process by maintaining a barrier between the ice and the warmer environment. Conductors, on the other hand, would not prevent ice from melting as they facilitate the transfer of heat.
Use clay,rubber, wax, seaweed and styrofoam

Stuff it into a styrofoam cup with cotton and aluminum wrapped around it and put heaps of salt on the ice cube
There is no indication that they will stop melting (technically, they really wouldn't stop even if the earth weren't warming). Much of the area of the ice caps has been observed to be accelerating in melt, in fact.
