This is an ITP swirl using Bramble Berry Lavender & Herb Fragrance and New Grape Mica. What is ITP? This is a soaper's abbreviation for "In the Pot". This means you don't actually swirl the colour through the soap, the colour is simply poured into the main pot and the colours mix themselves as you pour the batch from the main soap pot into the mould. A slab or log mould are best for this kind of soap, though vertical moulds can look really nice too.
The most important thing with ITP style colouring is to avoid overtracing the soap. If it is too thick, it won't swirl well and will clump instead of flowing. Also important is to use a fragrance or essential oil that doesn't accelerate trace. (Just check the notes on each of our fragrances so you know what to expect).
As this log is scented with Lavender & Herb Fragrance, we coloured our batch with a combination of Grape Mica (3/4 - 1 teaspoon moistened in a little oil and mixed into 1 1/2 cups of the traced soap for the swirl colour ) and Brites NG for Lime Green or the fresh green background colour.

If you are a beginner, we recommend you make a few batches before attempting this soap. For how to make soap from Scratch, please see our Cold Process Soapmaking Instructions. You can also watch Soap Queen's You Tube Series on Cold Process Soapmaking.
- If you are more experienced, you can follow the instructions below.
- Prepare all ingredients and mould as usual
- Prepare the New Grape Mica in a teaspoon of oil and remove any lumps
- Set aside a spare 750ml jug (or similar container up to 1 Litre) for the Grape Mica swirl colour
- Bring the whole soap batch to thin trace, and then pour approximately 1 - 2 cups of soap into the spare jug
- Colour this portion with the purple mica paste and briefly give it a blast with the stick blender - be careful not to overtrace - until you reach a colour depth you are happy with - go darker with purple unless you prefer a pale mauve
- Add suffient green colourant to reach the depth of colour you are happy with
- Now add the fragrance into the main pot and stir through thoroughly, but don't increase the thickness of the trace. You can use a hand whisk to do this
- Now work quite quickly - pour the purple portion back into the main pot
- DO NOT MIX THIS THROUGH AT ALL
- Still working quickly, pour the soap into the mould, moving along its length as you pour – the colours will mix as you do this
- By slightly moving the soap pot as you pour you can alter the pattern a little if desired

If you want a textured top, you'll need to work with a thicker trace, or wait until the soap begins to firm up in the mould. Then make the textured top and to avoid ashing, spritz liberally with Isopropyl Alcohol, then insulate well for gel. You can also cover with acetate once firm enough to lay this over the top without it sticking
