I made it! Just in time.. (right?)
Here is my hot process linear swirl soap, colored with AC, spirulina and annatto.
I'm glad I found some time for a third try, I think it's a lot better than the others. I did a simple Taiwan swirl, going back and forth first perpendicular to the lines, then parallel.
And here's my entry picture:
@amd I initially separated out half of my batch as an uncolored background, but I had a hard time getting all my colored batter in the mold because it started to harden on me. I think I might be in violation of the 1/2 rule now (especially since I only planed the top and not the bottom of the soap). Feel free to disqualify me if necessary
If anyone else wants to try this in HP, these are some tricks I learned along the way:
- make the linear swirl only in the top half of the soap, trying to make lines throughout the entire thickness of the soap will take too long and the batter will cool down.
-I used a piping bag to make the lines, then pressed the soap to make a flat surface. After that I would use a bamboo skewer to make the design. The soap is going to separate, but you can press it back together without harming the design.
-Make your lines uniform on top of each other (yellow on yellow, green on green etc). You're going to want to heavily plane the top and you might lose the pattern if different layers get mixed up (which happens when swirling).
-make sure you press the top tight and make it flat after swirling, otherwise you have to plane a lot off afterwards or you end up with holes in your soap.
-For me it helped to HP on a high enough temperature, so you have enough working time (I generally HP on low temps, so this might just be regular HP for some). Stay on top of your soap though, it might volcano (ask me how I know).
-And of course yoghurt!!
