Afternoon all.

I'm working on a new project and one of the components I will be using is ice either frozen into the shape of a block, cubed or crushed.

Part of the success of this project will be how long the ice remains frozen/solid and I have racked my brain trying to think of a new way to increase the effective shelf life of ice by possibly adding a refrigerant fluid or others.

As I believe there are a number of intelligent members here I wonder if any of you lot have any experience handling ice?

Thanks in advance for your kind suggestions and advice.
