Black Amber & Lavender LogBlack Amber & Lavender Log


This batch will fill our Wooden Loaf Mould with Silicone Liner comfortably, or you can use our Flexible Mould - Loaf (Regular) and have a little soap left over for individual moulds.  We divided the batch into two as our picture shows you for a diagonal two tone log.  We sliced half with our Flat Blade Cutter and the other half of the log with our Crinkle Cutter.

We have used Ultramarine Violet (you can also use Liquid Pigment Dispersion Royal Purple), Liquid Pigment Dispersion Black and White Pearl Mica to colour the log. The violet half of the log is unfragranced as Black Amber and Lavender discolours soap, so to overcome this we have only fragranced the black half.

This recipe makes a lovely, shiny smooth bar that has a lovely silky texture and good lather.



For how to make soap from Scratch, please see our Cold Process Soapmaking Instructions Page


  • Prepare log mould by lining it and propping it securely between phone books or similar, so that it sits on an angle ready for the first pour. (See below for more detail)

  • Bring the soap to light trace and then divide the batch into two containers - weigh each portion to ensure two equal halves

  • Colour the violet base layer to a dark purple and when at medium/heavy trace, carefully pour into the log mould

  • Using a small sample spoon or tea strainer, sprinkle a thin layer of White Pearl Mica over the base layer, carefully moistening it with the soap it is resting on

  • Check that the base layer has started to set up a little (it will be a little firmer) and then you are ready for the second pour
  • Now colour and fragrance the black top layer and when at medium trace, carefully pour over the back of a spoon on top of the violet layer

  • As the mould fills, carefully sit the log flat on the bench and continue filling until you have used all the black soap

  • Cover and insulate as normal

To make a diagonal line in the log mould you will need to firmly wedge the log mould on an angle.  Two stacks of old books work well, and then padded out the hollow under the base with towels or wedges of foam.  If using one of our Wooden Log Mould, secure the removable base and mould with tape or elastic bands at either end.   If you aren't confident doing this, you can use our Silicone Loaf Mould and pour the left over soap into a spare mould.

In a Nutshell:

  • Once the mould is wedged firmly on the angle, carefully pour the first half of the soap into it, level it off if necessary
  • Now WAIT!  The first half needs to set up a little to support the second pour
  • Colour and fragrance the other half taking care not to over-trace it or it will set up too soon
  • Once the soap is almost firm to touch, it's time to begin carefully pouring and re-levelling the mould again. I like to pour over the back of a spoon to ensure an even layer
  • Then pour the second colour from a very LOW height.  A light trace works best and try pouring over the back of a spoon or spooning it carefully over the first layer to avoid an uneven line.
