Teach Soap

I made a goats milk soap on Saturday using a guest size tray mold that says "Goatsmilk" on it. What is the best way to cut the soap after unmolding? I didn't have clean cuts, and the soap tended to split off from the bottom sides. I let the soap sit in the mold for about 20 hours, then I put it in the freezer for about 6 hours, then I unmolded it after letting it sit on the counter for about 5 minutes before cutting along the divided lines. I used my big butcher knife, and maybe it was too thick. How do I get the soap to look professional? Maybe my soap was a bit too soft, I'm not really sure. Do you think I should have let it sit in the mold for a couple of days before freezing and unmolding? I read somewhere about freezing the soap when using tray style molds.

Also, I used approximately 1 1/2 tsps of mermaid blue mica for the entire batch because I read on the mold that it holds 1.6 pounds. When I ran my recipe through the lye calculator, I experimented with different oil amounts to find a suitable overall capacity that would be a total of approximately 1.6 pounds. I ended up with 18 oz of oils and the rest in lye & goatsmilk liquid for a total of approximately 25 oz in total. The color seemed to come off a little when I cut the soap. Do you think the color will come off when I start using the soap after curing for 6 weeks?

Some colors can end up different if you are using milk. The whiter the base, the better the color.
For some of my smaller molds like the Milky Way molds, I use a pizza cutter.

I'm going to try the pizza cutter next time, which will hopefully be this weekend. My husband also bought me some wire, and he is going to fashion some handles on each end so i have my own wire cutter. Thank you so much for the tips!
