Crafting a Concrete Mold to Shape a Skull Vase To make a skull-shaped vase using concrete, start by creating a detailed mold of the desired design. Use a combination of paper mache and plaster to create a sturdy base for your mold. Next, use a mixture of water and cornstarch to create a smooth surface for pouring the concrete. After preparing the mold, mix together a batch of concrete using a ratio of 1 part cement to 2 parts sand. Add a small amount of water to achieve the perfect consistency, then pour it into the prepared mold. Use a wooden spoon or spatula to remove any air bubbles that form on the surface. Allow the concrete to set for several hours before carefully removing it from the mold. Once removed, use a wire brush to smooth out any rough edges and give your skull-shaped vase a polished finish.
