The best you can get is twisted hemp, Tommy.
It when cured burns nice and hot and a large coal.
Susan Wallace used to sell it in 100 yards balls. (Silver Shuttle, Memphis TN, but not sure if they are still in business.
It stays twisted when burning.
I tried in in potash, but needed a good wash afterwards or it burned too fast and fizzled.
Tried it in gunpowder, boiled , then laid to dry. Worked V well. brush it through your hands after drying.
takes the bits off the surface that can fizzle off where you don't want them.
A handful of gunpowder to a gallon or so of water.
Any slow match should be laid to dry, otherwise the solution runs to the ends if hanging.
Never used lead acetate myself.
It slows the burn rate.
Mine burns an inch in 5 minutes. Wood ashes in solution, and matchcord boiled in it works as well as most.
