I'm making liquid shampoo using tussah silk that I dissolved into the lye water. The paste seized within 10 minutes of hand blending. Now, I'm cooking the paste on my slowcooker and it seems to be drying out in parts, not cooked. The parts that touch the walls of the crockpot becomes like wax and they don't melt. I've been cooking for 2 hours and no change. How do I save this? Thank you!
