I prefer the lather of an HP castile over a CP castile. Hp somehow makes for a creamier lather. I don't think there would be much difference in the hardness over a long cure time between HP or cp though....should be pretty much about the same.
i did my first castile and it got so hard that a day after i made it, i couldn't cut it and a week later i couldn't break the bar in half with my hands. i made one for me to use and one that i have been letting cure to see the difference. i have no idea why it got so hard so easy and so fast? it was pure OO and the only things i added were chlorella powder and a yellow powder i can't remember the name of right now. maybe that did it?
