Strictly speaking, chemicals are always used to tone coins, even naturally toned ones.
Not entirely true. Many, many people use an gas oven and/or even the top burners to tone coins. Some lay coins out in the sun, changes in temperature and the air does the rest.
And as noted some use a Propane, Butane and even Alcohol burners to tone coins.
In a way your correct since it does take an ouside source, such as even moisture in the air, to tone coins. The gas from a stove too is sort of a chemical used to tone a coin.
Most of the ones shown in your link to those toned coins do have that torchy appearance.
