Hi Melissa,

You can use plasticine to sculpt your model for making a silicone mold as long as it's SULPHUR-FREE. Some brands I recommend are:




If you have a brand that you already own and love using that contains sulphur, you can still use it – just seal the surface of the clay model with Krylon's Crystal Clear Acrylic spray - several coatings are usually required.

Let me know if you have any more questions!

Happy making,
