How to make a Silicone Mold?

Making a silicone mold is surprisingly simple and requires only a handful of components. And while professional equipment gives you more options, there are also plenty of at-home uses for silicone molds. The components needed to make a silicone mold are:

Liquid silicone: Silicone for mold making is widely available and usually comes in two parts that must be mixed together immediately before 

use.

A container: The liquid silicone is poured into a container, which should be larger (but not much larger) than the master pattern. In many 

cases, a new and suitably sized box can be made on demand using e.g. wood or cardboard.

A master pattern: The master pattern is the original object that you will duplicate using the silicone mold. A master pattern can be an existing object,  or a newly made item fabricated using a 3D printer.

Mold release: Mold release is a spray-on liquid used to prevent the mold from sticking to the watertight container,and also to prevent casting materials from sticking to the inside of the mold.

Casting material: The material poured into a silicone mold can be anything from polyurethane to melted chocolate.Clay (optional): Clay is only required when making a two-part mold.
