Had a lovely surprise when I cut a column soap made on Wednesday. I used a Pringles tube and fashioned a thin tube out of a sheet of acetate that I had to put in centre for the black soap. It was messy to pull out the inner tube but I managed it, my batter was a bit too thick and I had to work fast to swirl it but some of the cuts are really pretty! Its goats milk kefir with activated charcoal.
