Why is finely divided ice used in the experiment of determination of specific latent heat of fusion rather than large ice?

So you can actually witness the moment when the ice starts to melt. It's important that you see when it FIRST begins and not a moment too late. With a large block of ice, you'd barely be able to see it begin to melt because its change wouldn't be as distinct. Ice would melt but the block might just start looking more wet. It's just easier to watch individual ice crystals start melting because then the separation between them begins to narrow.
