Geode silicone mold set for isomalt or soap, three sizes.
Use this set of three geode silicone molds to make edible geodes using isomalt or fondant, or for making geode rock soap.
There are three different sizes of molds, each has a different size crystal as well. They're approximately 2", 2 1/2" and 3" across. but the shapes are irregular because they're made with real geodes.
To make them the way they look in the photos, you'll need to use a combination of isomalt and fondant or gumpaste. Instructions will come with the set.
You can also make them using all fondant or gumpaste, then paint them with shiny metallic food colorings.
