To stop ice from melting you are going to have to stop heat getting to it so you need to wrap it in a good insulator. Wrapping the ice in bubble wrap or putting it in a box made from polystyrene foam would work well, the thicker the insulator the better! A waterproof insulator is good because water is quite a good conductor of heat, if you say wrapped it in straw then the water released from the first bit of ice would soak into the straw and make it a less good insulator allowing more ice to melt. You could get around this by putting the ice in a plastic bag and wrapping the bag in an insulator that wasn't waterproof. For any container the more ice you have in it at the start the longer some will last. Ice can be kept in a high quality vacuum flask for quite a long time but if you are looking to make it yourself then it would be far from simple.
It's not. When you put ice in a glass the glass quickly becomes cold. Glass actually is a good insulator because in the summer when you have the air conditioner on in your house, glass keeps the hot air out and the cool air in.
Because saw dust is a decent insulator, acts like a natural cooler.

to make an insulator prevent ice from not melting is to use tinfoil and dirt.

No, Ice is a good insulator and copper is a very good conductor
The ice layer act as an insulator.
Ice is readily available for them, and it is a good insulator.
The jute acts as an insulator and it slows the melting of the ice.
