I'm sure your lye is at least good enough unless you left in open overnight or something. That is less than 27% lye concentration. If you soaped it cold, maybe it separated to some extent. Did you get a good trace before pouring or was it thin? Is the top different from the bottom? Maybe tongue test both.How can I tell if I have bad lye? I ask because I made soap 24 hours ago and it is still super soft
