If you contact a stock agent (you may have another name for these companies
- they supply fencing materials, rope, farm supplies to farmers and
frequently also as agents for sale of livestock) they will be able to
identify the twine and what it is comprised of.  Much jute twine has been
replaced by a black polypropylene twine which is presumably more durable but
which I would not like to ignite in my smoker.
