How was fires started in Colonial America?
Some rocks, like flint, when struck together will create a spark into kindling. Gunpowder had been invented and could be used to light a fire with a spark. Fire can be started by friction using a sticks and spinning on against the other using a bow like arrangement. In many cases the colonials did not let the fire go out. You would "bank" your fire with ashes so it would be there in the morning. People would share coals to start new fires. People would leave a candle burning so they could start a fire in the morning. The technology in firearms made the use of flint a dependable fire starter with the development of "lighters" that used the flintlock from the muskets. .
