My Inspiration for Rose Gold Mosaic Soap Bars

Well we’re only three months into this year but I am loving our mosaic soap challenge projects.

Each project showcases a different mosaic soap technique and this month’s technique is cookie cutter mosaic soap.

This technique is so quick and simple, I’m referring to it as the mosaic soap ‘cheat’s version’.

Basically it involves using a cookie cutter to cut a shape from a slab of mosaic soap tiles and then embedding the mosaic soap shape into a larger soap bar.

Then you just pour some more liquid soap base over and around the embed to ‘grout’ it in and you’re done!

For this project, I have paired a heart-shaped cookie cutter with gorgeous rose gold coloured mica, but you can choose whatever shape cookie cutter or coloured mica you want – imagine the possibilities!!

Let’s get started!

What You Need to Make Rose Gold Mosaic Heart Melt and Pour Soap Bars

Melt and Pour Soap Base

Melt and pour soap is sold as large blocks that you can cut up and then weigh out the amount of soap you need.

I used white melt and pour soap base and clear melt and pour soap base to make my rose gold heart mosaic soap bars.  Each of my bars weighs approximately 70g (~2.5oz).

The mosaic soap tiles were poured from clear melt and pour soap base, displaying the beautiful shimmer of the rose gold mica. 

The base soap bars were made from a combination of clear and white soap base (at a ratio of 80% clear and 20% white), as I wanted my base bars to also have shimmer, but be paler and more opaque than the mosaic tiles.

Soap Moulds

To make mosaic melt and pour soap bars you need two moulds, one for the tiles and one for the remaining bar (base bar) of soap.

This mosaic tile mould makes six different patterns of mosaic tiles.  For this project, I used the two abstract mosaic shape sections and the square tiles section.

Live outside of the United States? You can also buy this mosaic tile mould from AliExpress.

I used three geometric-shaped soap moulds for my base bars – circular, square and hexagonal.

I did this to demonstrate how this technique looks with various shaped base bars. 

A Cookie Cutter

You can use any shape cookie cutter for this project, but it needs to fit inside the cavity of your base soap mould.

I suggest using nested cookie cutters as then you will have a number of different sized shapes to choose from – one of them is bound to fit!

Plastic or Rubber Scraper

You will find filling the mosaic tile silicone mould much easier if you have a rubber scraper on hand to distribute the melted soap base evenly across the mould.

Soap Colouring

I used a rose gold coloured mica to colour my heart mosaic soap bars.

If you don’t have rose gold mica, you can make your own my mixing gold and raspberry-coloured micas at a ratio of 3:1.

Essential Oils or Fragrance Oils

Scenting your soap is optional, but most of us prefer a pretty smelling soap bar.

I scented my heart mosaic soap with a blend of Wild Orange and Ylang Ylang essential oil, but you can feel free to use your favourite combination of essential oils or your preferred fragrance oil.

Small Glass Measuring Cup

I highly recommend using a small glass measuring cup to pour the mosaic tiles.  An espresso measuring cup (used by baristas) is ideal as it has a double spout, a wooden handle, and can withstand high heat.

Alcohol in a Small Spray Bottle

Alcohol (rubbing alcohol/isopropyl alcohol or vodka) has a number of uses when making melt and pour soap:

• Spraying the soap with alcohol once it’s poured will remove any bubbles sitting on the soap’s surface.
• Spraying alcohol between soap layers helps them adhere together.
• Spraying the soap mould with alcohol before pouring the soap helps the soap spread evenly across the bottom of the mould.

Additional Materials Required

Kitchen Scales – I’ve used grams in this recipe because the amounts are easier to manage compared with ounces.  Most kitchen scales these days are interchangeable between grams and ounces.  Check your scale’s instruction booklet for how to change your scale to measure in grams and then change it back when finished.

Glass Measuring Jug – You will need a larger (250ml/8oz) measuring jug to melt the white melt and pour soap base.  I have a separate glass measuring jug dedicated to creative projects (soap making, lotion bars, lip balm etc) to avoid any cross-contamination of non-ingestible ingredients with food.  I recommend you do the same.

Metal or Bamboo Skewer – Skewers are super handy for stirring and can be easily cleaned or disposed of.  A wooden popsicle stick, or disposable spoon will also suffice.

Paper Cup – A wax-lined paper cup is used to collect the unused soap base after you have poured your base bars for use later to ‘grout’ around your mosaic heart embeds.

Cotton Buds – You will require cotton buds/swabs during the soap ‘grouting’ stage to clean up any soap base spilled on the mosaic soap tiles.

A Toothpick – A toothpick is required to perforate the mosaic heart embeds.

A Tray Lined with Greaseproof Baking Paper – Position the mosaic tile mould on a piece of greaseproof baking paper on a tray before pouring to allow for easy cleaning up (there will be drips) and transport while the soap is setting.

Microwave or Double Boiler – Melt your soap base in either a microwave or a double boiler.

To make it easier for you to grasp the process, I created a video tutorial about how to make Rose Gold Heart Mosaic Soap Bars.

How to Make Rose Gold Heart Mosaic Soap Bars.

Want your cookie cutter mosaic soap to look like mine?

I used a combination of clear melt and pour soap base and white melt and pour soap base scented with Wild Orange and Ylang Ylang essential oils and tinted with rose gold mica to make three base soap bars.

I made a little more than I needed and poured the leftover soap base into a paper cup to be used later.

I then filled three sections of a mosaic tile silicone mould with clear soap base also tinted with rose mica and scented with Wild Orange and Ylang Ylang.

I carefully removed the mosaic soap slabs from the mould, ensuring they stayed in one piece.

I then used a heart-shaped cookie cutter to punch a heart-shaped mosaic soap embed out of each mosaic soap slab.

After perforating them with a toothpick, I positioned the mosaic soap embeds on top of the base bars.

Finally, I re-melted the leftover soap base and poured it around the mosaic soap embeds to ‘grout’ them in.
