What I have I done wrong - tallow soap

[Lillipad]

I’d love to understand what’s happening here? I’m worried maybe I didn’t mix the tallow and lye enough and now there’s bits of tallow spread throughout the soap?

I’ve only just cut it after 13 hours in the loaf.

It look like stearic swirls. Maybe your batter was too cool (or the lye was too cool compared to the oils) and the stearic solidified somewhat?
