You can use any recipe and sub the pine tar for 20% of your oils . Pine tar is on some calculators . Be prepared to work fast, I mean have everything ready to go , it moves fast . You might want to have somewhere to put the mold for a while , it smells , not horribly , but not perfume either. The pine tar I use has a nice smokey scent when it is cured. If you have any questions , feel free to pm me.
PS I used lard , co , po , and oo . I superfatted at 10%. It is a very soothing soap.
