Although not accurate, I suggest the following recipe.
Making JWA
1. Mix 3L canola oil(Vegetable and animal oils) + 3L KOH 20%.
2. Mix with an electric drill for perhaps 1 to 4 hours. (Until it becomes like mayonnaise, It could be over 4 hours.)
3. Let it aged for 3 days.
4. Add 10.5L of soft water and melt.
Making JS with KOH 20%
1. Mix Sulfur 99% 750g + KOH 20% 3L
2. Heat while stirring.
3. If sulfur is completely dissolved, it is 25% JS.
I wish you success. I want to continue to advise you guys.
It would be better if you could show the progress in a photo.
