Cut up your soap into small cubes (for easy melting) and then place them in a glass measuring jug. Melt in the microwave in short bursts of 30 seconds, stirring well in between. Repeat until your soap is melted (watch it carefully, don’t let it boil!).
Divide into paper cups and add the soap colouring and essential oils. Stir well with a skewer until the essential oils are well combined and you have an even colour. If your soap mixture has lots of bubbles in it, spray the surface with alcohol and then gently stir again to get rid of the bubbles.
With your cup of melted soap in one hand, and your spray bottle of alcohol in the other, very carefully pour a small amount of soap mixture into a template on the macaron mat. Immediately spray the soap with alcohol, doing so will help your soap spread out to the edges of the template.Continue pouring and spraying until all templates on the macaron mat have been filled.
If there are bubbles present on the surface of your soap, a couple of sprays of alcohol should remedy this.
Any overflow of soap outside the lines of the templates can be scraped or snapped off once the soap has hardened.
Set your soap aside to harden overnight.
To release your soap gently bend back the silicone macaron mat and your soap bars should pop right off.
