Pink at last - Using fresh Rumex oil
It turned this lovely light pink. There is alway a bit of yellow in it where it gells, but the color tends to veer towards pink as it gets exposed to air. It is pretty amazing to me that the small brown balls and the soap and pink hearts are made with the same material, rumex oil, but just different batches.
I think the conclusion has to be that fresh oil will produce pink, but as it gets older the color will get darker and eventually turn brown. It doesn't take a lot of oil to color the soap. I've usually used 15-20 grams in one recipe of 500-700 grams, which is less than 5% of the Rumex oil to the amount of other oils used. That is very different from the amount of oil that I use when I've used Alkanet oil. But I really need to try to make soap using less of that. Could be the next project. There is always demand for Lavender soap.
For decoration, I used Heather (Calluna) and Yarrow (Achillea millefolium) on top. Those two are actually very well suited as a decoration on top of soaps because they keep their color well and don't turn brown easily since they sit on top of the soap and don't really get wet. It actually turned into a very pretty and girly soap.
Now I need to make yet another one, using this very Rumex oil, except it has now been infusing for something like 8-10 weeks. In fact I just poured it into a jar to discard the Rumex root. The oil is a lovely, lovely bright golden yellow and it smells lovely. I have been using it on my face at night and I swear that it does make my skin feel and look better. Of course my face looks a bit yellow. The oil must be chock full of antioxidants. But since my darling husband hasn't even commented yet (other than to tell me I'm beautiful) I'll keep using it. And btw I'm almost up to 100 grams of cleaned Eiderdown. Only 900 to go.
