How to make silicone moulds for wax melts, soap making, fondant and more!

A couple of years ago I started to sell wax melts as a hobby, when I started making my own moulds things really took off! It meant I could make just about anything, people loved the themed melts and I couldn’t keep up with the orders! I decided to call it a day as I have two children under the age of 2, I just didn’t have the time or the energy! I got so many messages asking how I made the moulds so I thought I’d do a blog post on it.

I hope this doesn’t seem complicated because it’s really not once you get the hang of it.

You’ll need the following to get started

Oven bake clay – I find this one to work the best

1kg silicone kit – This one is a great kit to practice with. It should make a 10 cavity mould (approx) What I would personally do is make 10 separate designs, then make bigger moulds for the designs that sell the best

Lollipop sticks

Sellotape or a sheet of sticky back plastic

Rolling pin

Plastic food containers – the cheap flexible ones you can buy from the places like the pound shop. The dimensions of the container will be the size of the mould (don’t worry about the depth)

And things to design your mould, now is the time to get creative! Use things like
Cookie cutters, charms, small moulds to modify
(i’ll do a separate post on all the different items to use to create different moulds)

First of all roll out some clay (I used stacked lollipop sticks in order to roll it evenly)
Use a bit of flour if you find it sticking
Now time to get creative and make the clay templates. For example for the unicorn template I used a cookie cutter to cut out the fancy circle. I then pushed clay into a small unicorn mould (linked above) and placed it onto the template, gently pushing it down so it’s secure.

For the lollipop I pushed a clay charm (linked above) into a clay template I cut out using a cookie cutter

For the star template I used a stamp and the ginger bread man was cut out using a cookie cutter . I used a toothpick to add the face.

You can make anything using a custom cookie cutter

Now cut the bottom off the food container to make a frame, don’t make it too shallow (keep reading you’ll see why)
Lay down a sheet of sticky back plastic (sticky side up) and place the frame in the middle.

If you don’t have a sticky back plastic sheet then you can lay overlapped sellotape down to create one like I did.

Put the baked clay templates in the middle
Fold up the edges of the sellotape. Leave the top open
Mix the white and the red silicone according to instructions (After I’d made a couple of moulds I didn’t look at the instructions anymore I just went by the colour. Basically the red liquid is the hardener. So the more you add, the less flexible the mould will be. I knew if my mixture was a baby pink colour then it would work great.
Once it’s mixed, quickly pour it over the clay templates. Cover them evenly.
Don’t worry about bubbles, mine always looks like this
Leave until the mould has set. Once set, remove the tape and the frame and you’ll have your mould! Trim away an excess silicone
You can then use the moulds to make more clay templates and repeat the process to make even bigger moulds for your best sellers!

Good luck


  • I love this! Definitely going to try it out. Not sure how it’ll turn out, I’m terrible with clay.

    • You’ll be great once you get the hang of it! There’s tonnes of cutters / stamps etc etc to help create whatever you wish! Let me know how you get on 🙂
