I’m using a bit of the lighter one in the shower and it has possibly faded a little bit. I will need to dig one of the darker ones out of storage to check on the color.I made a tester (see above in post #13 above and was aiming for soap #4.
Made it exactly the same way but increased the size of the mix x 5. Used the same indigo, with the exact proportions, same heat etc. and the soap turned out a dull pale slate grey.
The heat infused oil had been sitting in a glass container for a while but I mixed it well.
So disappointed.
@Mobjack Bay has your synthetic indigo in the post from feb 2020 faded at all?
