There are several alchemical texts that refer to tin salt as fuel for "ever-burners" or lamps that always stay lit, although it was proven that these lamps only light when they come in contact with air, so that when a door is opened, the lamp lights at once, giving the illusion that it's been lit ever since it was placed there. So in conclusion, tin salt, if extracted correctly, should in fact, burn when in contact with air.
Here is one text that gives a wonderful explanation of this:
Phosphorus is the element that ignites spontaneously in air due to its high reactivity. When exposed to oxygen, phosphorus can catch fire and burn brightly, producing light, hence the nickname "light-bearer."
When an element burns in air, it reacts with oxygen to form a compound known as an oxide. The specific oxide formed depends on the element being burned. For example, when carbon burns, it forms carbon dioxide (CO2) and when magnesium burns, it forms magnesium oxide (MgO).
Magnesium burns in air and nitrogen to form magnesium oxide (MgO) and magnesium nitride (Mg3N2), respectively.
One chemical property of hydrogen is its ability to react with oxygen to form water. Hydrogen also exhibits the property of being highly flammable when exposed to air or an oxygen-containing atmosphere.
Phosphorus is an element that emits a distinct garlic-like odor when it burns.
Phosphorus is an element that turns white when exposed to air. When pure, it is a colorless and transparent waxy solid.

oxygen
Magnesium is the element that gives dazzling light when it burns in air. This is due to the intense white light produced as a result of the combustion reaction with oxygen.
Water, aka H2O
When an element burns in air, it reacts with oxygen to form a compound known as an oxide. The specific oxide formed depends on the element being burned. For example, when carbon burns, it forms carbon dioxide (CO2) and when magnesium burns, it forms magnesium oxide (MgO).

Iodine
One chemical property of hydrogen is its ability to react with oxygen to form water. Hydrogen also exhibits the property of being highly flammable when exposed to air or an oxygen-containing atmosphere.
iron is one anything that can be oxidized will rust
Oxygen is the element in the air that is needed for coal dust to burn. When coal dust is exposed to oxygen and heat, it can ignite and burn.
