I'm obviously very new to soapmaking so please forgive my ignorance. Here goes... is there an alternative to the "zap" test to see if the lye is cooked out - is this what the zap test is for? I'm really not thrilled with touching my tounge to lye (or am I misunderstanding the "zap" test). I think I'm over cooking my soaps in cphp process and would like to fix the problem if possible. Any help would be appreciated.
