Melt and pour soap is basically melting a pre-made soap base and then pouring it into a soap mold, hence the name! Although some soapers consider using this method as ‘cheating’, I find that there are some techniques where melt and pour is the more suitable soap than cold process soap. For example, where a design asks for clear cut straight lines or when you are using molds with intricate designs. More on soap molds, check out this post here.
In addition, melt and pour soap also comes as a clear soap base (also known as glycerin soap), which is an advanced soap making technique if you want to do this yourself. In the past few years, many kinds of melt and pour soap bases have become available, such as goats milk, olive oil, shea butter, honey, and even a wobbly jelly-like soap base! Personally, I like using melt and pour soap bases because you can create some pretty cool soaps with it, plus your soap is ready to use as soon as it sets. Great for last minute gifts!
The technique of melting and pouring the pre-made soap is very simple. Cut up the required amount of melt and pour soap base into small cubes and place them in a heat proof glass jug (i.e. Pyrex, available at supermarkets, Briscoes or the Warehouse). In short bursts of no more than 20-30 seconds each, melt the soap in your microwave. Be careful your soap does not boil! If you don’t have a microwave, you can melt the soap on the stove using the double boiler method (placing one smaller pot inside a bigger pot of water).
Once your soap has melted, add your fragrance and colour and give it a good stir. You can use essential oils or skin-friendly fragrances. To colour your soap, you can use special soap dyes or powders, micas, or liquid food colouring. Note that colours added to a white soap base will become pastel coloured. To achieve bright vivid colours, you will need to use a clear soap base. And if you find your soap has hardened in the meantime, just pop it back into the microwave again for another 20 seconds.
Carefully pour the soap into your soap mold. If there are any bubbles on the surface, you can disperse them by spritzing some isopropyl alcohol (available from pharmacies) on it. Leave the soap to harden fully before removing from the mold.
Because melt and pour soap contains glycerin, a humectant, which attracts moisture, it is important to wrap your soaps in glad wrap as soon as they have cooled down and hardened. Especially here in New Zealand when it can be very humid, you’ll find beads of water on the surface of your soap if you leave them unwrapped.

Hi, do the food colouring gels work better than the food colouring liquid?
I’m not exactly sure what is in the food colouring gels, I’m guessing some kind of sugar? I’ve never tried it out and I’m not sure how well they would work, but why not give it a try?
Hi there, can the mica swirl technique be used on top of melt and pour soaps?
Unfortunately you won’t get the same effect, but it will still be nice and sparkly!
does food coloring stain? just curious as would love to grab some in my food shopping tomorro
Not in such small quantities! So go ahead and splurge on lots of colours tomorrow!
What is the usage rate for food colouring in MP soap?
Hi Gracie! The cool thing about using melt and pour bases is that the colour stays true and doesn’t change after cooling down. Depending on how much soap you have, I’d start with a drop and then add more if needed. Food colouring is quite strong, so it’s easy to to overdo it. Remember, you can always add more but you can’t take away! 😉
