Details

Bramble Berry Fragrances


Create scrubby, moisturising soaps using exfoliating additives to slough off dry skin cells and re-vitalize your skin.  The Pink Himalayan Salt will give a robust exfoliation, and the Adzuki Beans and Spa Minerals are smoother for an all-over re-vitalizing of your skin. 

This tutorial also comes in a Kit, which you can purchase here.

There are three bars in the kit, and two of these are featured here. No colour is needed in these natural Spa Bar Melt and Pour Soap - just wrap them when set as the salt can tend to draw moisture to the soap.

We use our Heavy Duty Oval Mould Here or you can make a dozen at a time in our 12 Bar Oval Silicone Mould.

To all 3 styles of spa soap you'll need:

 

Aussie Soap Supplies

Equipment

Stirring spoons or spatulas
2 x microwave safe jugs - each needs to hold 500 - 750ml

Method for the Spa Mineral Bars:

 

  • Cut 240g of soap base into 1 cm cubes and place in a microwave safe jug. Melt in the microwave on medium – low in 30 second bursts, stirring between each 30 seconds. If you have a thermometer heat to approximately 60°C, heat until it’s just melted
  • It’s important to avoid lumps when adding powders to soap, you can use fragrance, glycerine or sodium lactate to moisten clays. As this is a kit, this is not supplied, just use some water – add 2 teaspoons to the tablespoon of clay.  Mix into a smooth paste ready to add to the melted soap. If you have some glycerine on hand you can use that ☺.  The graphic above shows the soap at the back with little lumps of clay, this causes no harm, but looks a little displeasing
  • Add the clay slurry/paste to the liquid soap and stir the soap carefully to ensure you don’t incorporate any bubbles into it
  • Now add the fragrance or essential oils – we suggest you use 10 to 20 drops per soap (depending on how strongly you like your soap scented), so for 4 soaps use up to 60 - 80 drops (this is approximately 1/2 to 2/3 teaspoon). Stir well to combine
  • When the soap is a little syrupy (like warm liquid honey) it’s time to pour – you can stir occasionally until it reaches this stage. By waiting it means the clay particles stay evenly distributed in the bars.
  • Leave in the mould until completely cold (several hours)

What's this? This is what happens if you don't moisten the Spa Minerals (and clays) before adding to the melted soap!

Method for the Adzuki Bean Bars:

  • Cut 240g of soap base into 1 cm cubes and place in a microwave safe jug. Melt in the microwave on medium – low in 30 second bursts, stirring between each 30 seconds. If you have a thermometer heat to approximately to 60°C, heat until it’s just melted

  • Stir the soap carefully to ensure you don’t incorporate any bubbles into it

  • Now add fragrance or essential oils – we suggest you use 10 to 20 drops per soap (depending on how strongly you like your soap scented), so for 4 soaps use up to 60 - 80 drops (this is approximately1/2 to 2/3 teaspoon). Stir well to combine

  • Arrange a single layer of adzuki beans in the base of each more cavity (this is 80g of beans)

  • Carefully pour a thin layer of soap over the beans - which is just enough to cover the beans. Allow this to sit for a minute or so, then top up each cavity with soap. This method will stop the beans from floating up in the liquid soap

  • Leave in the mould until completely cold (several hours)

Method for the Pink Himalayan Salt Bars:

  • Cut 240g of soap base into 1 cm cubes and place in a microwave safe jug. Melt in the microwave on medium – low in 30 second bursts, stirring between each 30 seconds. If you have a thermometer heat to approximately 70°C, heat until has melted. This is a little warmer as the salt brings the temperature down quickly. It can also be helpful to warm the salt crystals

  • Stir the soap carefully to ensure you don’t incorporate any bubbles into it

  • Now add fragrance or essential oils – we suggest you use 10 to 20 drops per soap (depending on how strongly you like your soap scented), so for 4 soaps use up to 60 - 80 drops (this is approximately1/2 to 2/3 teaspoon). Stir well to combine

  • Now add 100g coarse Himalayan Salt into the soap jug – it’s heavy so it will sink to the bottom. Stir to allow the soap to coat the salt crystals. This helps reduce surface moisture as the crystals come in contact with the air

  • Immediately spoon out a quarter of the salt from the bottom of the soap jug into each cavity of the mould. Then stir to mix the remaining soap and any left over salt crystals

  • Pour the rest of the soap straight from the jug into the mould cavities, topping each one up to the to brim.

  • Leave in the mould until completely cold (several hours)

Unmoulding:

  • Allow several hours or overnight so to completely set - if the soap is still warm unmoulding will be difficult

  • Carefully use a spatula or bread and butter knife to release the air lock around the sides of the soap as pictured below

  • Invert the mould, and use your thumbs to add pressure from the edges of the cavity and into the centre - the soap will drop out onto the work bench

  • If the moulds need cleaning before using again, do this now and repeat procedure subsequent pours

Wrapping:  The Himalayan Salt may draw moisture to the bars and glycerine beads will appear on your soap.  Wrapping soon after unmoulding will prevent this.
