Instructions
Set out all of your equipment and ingredients ready to be used.
Base Soap Bars
Weigh out 160g (~5.65oz) of clear melt and pour soap base and 40g (~1.4oz) of white melt and pour soap base and cut it up into small cubes (this includes wastage).
Pour 50g of liquid soap base into three cavities, resetting the scales to ‘0’ between pouring each cavity.
Spray the surface of the soap with alcohol to remove any bubbles.
Pour the remaining soap base into a paper cup to be used again later as ‘grout’ around the mosaic tile embeds (this ensures that the grout soap will have an identical colour and scent to the base soap bars).
Melt your soap base as per the instructions in a microwave or double boiler.
Add the soap colouring (liquid soap colouring or coloured mica) and fragrance oils/essential oils (if using) and stir well.
Working quickly, pour the liquid soap base into three sections of the mosaic tile silicone mould.
To ensure all of the tile cavities are filled evenly, spread the soap base around with a rubber scraper and spray alcohol to break the surface tension and remove any bubbles.
Set the soap aside to set for 1 hour.
Once the soap is set, turn the mosaic tile mould over and carefully peel away the silicone mould, ensuring the slabs stay in one piece.
Using a cookie cutter, cut an embed from each of the three mosaic tile soap slabs. Do your best to ensure the tiles around the edge of the embed are not too small.
Take a toothpick and punch holes around the mosaic tiles of each embed (where the grout lines will be).
Mosaic Soap Bars
Once fully set, tear the paper cup away from the leftover soap base and cut it into cubes.
Carefully remelt the soap base in a microwave or double boiler.
Spray the mosaic soap embeds and the surface of the base soap bars liberally with alcohol.
Pour a tiny amount of soap onto the top of a base soap bar and position a mosaic soap embed in the middle of the bar of soap. Liquid soap base should seep through the toothpick holes in the embed to help seal it into place.
With your melted soap base in one hand, and your spray bottle of alcohol in the other, gently pour the liquid soap base around and over the mosaic soap tiles to ‘grout’ them into place.
As you pour, spray the soap with alcohol to help it fill the small gaps between the mosaic soap tiles, and to remove any bubbles.
Clean up any ‘grout’ soap covering the mosaic soap embed immediately with a cotton bud dipped in alcohol.
Repeat steps 5-8 for the remaining two soap bars.
Allow the soap bars to set overnight and then demould them by pushing from the bottom as you peel back the silicone mould.
