I collect all the pine pitch that I come across and put it in a can. When I get home, I melt it down and put it in a bigger can, I heat that up and melt them together. I keep doing that until I get enough pitch to make a batch of glue. I collect the soft, after several heating, all the volital oils are gone or I keep it cooking until they are. Then add the beeswax and charcoal. You can find beeswax at sewing supply stores and hobby shops. Do not use parafin, the glue doesn't get hard. Bill
