I'm intrigued by pine soap. I have a pine/fir tree that's oozing sap. Some has hardened, some still soft to the touch. It's an old tree, and the gash/slash is huge, and it's oozing good amount or sap. So I've been thinking of incorporating it to a batch of soap. I've read a bit online about harvesting and making pine tar/pitch, but: 1. Can I make soap just using the resin, not tar? I'm assuming both hard resin and soft resin will melt to a same thing over double boiler? What I've understood is that pine tar is pine resin+ pine charcoal. 2. any big difference in 'health' benefits between using tar vs resin? 3. My resin only has a slight aroma. Would this still be a good one? Thanks!
