I believe this was produced by destructive distillation of pine wood. Heat pine twigs, shavings, chips, needles, bark, small branches &ect. strongly over a fire in an airtight container equipped with a vent tube leading to a condenser. One of the fractions that comes off is tar, another should be turpentine, there are also more volatile fractions like wood alcohol and possibly acetone.

tar for hemp and marline
Here's an old note by Gene Smith from the
Baidarka mail list, with a recipe for pine tar slush: From: Gene Smith Subject: baidarka Pine Tar Date: Wed, 7 Oct 1998 A typical "downeast" deck finish formula from Maine: 1 quart Turpentine 1 quart Boiled Linseed Oil 1/2 pint Japan Drier 1/2 pint Pine Tar I suspect that "mast slush" and other slush formulas had a bit more pine tar in them. I just made up a half-gallon of this formula to paint on my cart used as a prop at Texas Renaissance Festival, which is, of course, built like a little boat on a big wheel. Think I'll put it on my homemade wood and leather clogs as well. Pine tar is one of those smells you either hate or love. Sailors used to paint it on hand sewn canvas clothes for a water proofing of sorts - hence the reference to them as "tars". Capt. Pete Culler in various places in his books makes a very good case for using something like this rather than paint on the inside of working skiffs. While it probably wouldn't "waterproof" canvas covering as well as more modern paints, there is at least one instance I know of where pine pitch was used to seal up a catamaran that successfully went transatlantic.

Can be obtained from farm supply outfits at a much cheaper price than at boatie shops...if they have it. Or search the web for a mail order place. You are after a mixture called 'slush'. Search under that too. Or post an e-mail to one of the Maritime Museums and see if their rigging shops will provide you with a recipe. http://pages.sbcglobal.net/djf3rd Tales of a Boat Builder Apprentice |

You can still get Stockholm tar at veterinary and horse supply houses.
About the only use for it these days is a remedy for thrush on horses' hooves.

For rigging served with nylon (tarred nylon seine twine is good) Toss says Net Dip from the fishery supply store works good.
