Things You'll Need
Desired mold shape: vase, piggy bank, statue
Large cake pan
Looking to make an ice sculpture for you upcoming party? Craft stores sell premade molds in the shape of hearts, swans and other generic shapes. If you want a unique ice sculpture to go along with the theme of the party, you will need to make it yourself. If you follow these steps, you can make a mold in the shape of anything.
Take the item that you want to make the mold of and cover any holes with Scotch tape so that the latex material will not go down into the item.

Lay the item onto the foil-covered cake pan.
Paint a layer of liquid latex over the item and two inches around it onto the pan. Let it dry for about 40 minutes or until it is completely dry.
Add a second and third layer and let dry. Add a forth layer and let it almost dry. You want it to still be sticky.
Cover the item in a layer of first-aid gauze. This will help the mold to be more sturdy.
Add four more layers of liquid latex on top of the gauze, letting each layer dry before adding a new one. Let the whole mold dry for 24 hours.
Dust the outside of the mold with talc powder. Peel the latex mold off of the item. It should come off easily; if it is still sticking, let it dry for a few more hours before retrying.
Dust the inside of the mold with talc powder. This keeps the mold from sticking to itself.
Lay the item on the cake pan again, but this time with the other side up. Repeat the whole process to make a mold of the other side of the object.
