what is a spirit lamp and what does it do

Just like an oil lamp burns oil, a spirit lamp burns spirits, such as ethyl alcohol. Thus, a spirit lamp is also known as an alcohol lamp or an alcohol burner. You can find them as a regular part of laboratory equipment.

Many are made with glass or metal and have a wick sticking out the top, which, when lit, produces an open flame creating both light and heat.

How Does a Spirit Lamp Work?

When using an alcohol burner, you need to use caution because you’re handling an open flame. Also, the alcohol you use releases a tiny amount of carbon monoxide, so ventilation is necessary.

You also need to make sure there are no cracks in your spirit lamp for safety reasons and ensure your spirit lamp’s proper function. Many of the alcohol lamps out there use pressure from the alcohol as it reacts to changes in temperature to get the fuel up the wick and power the lamp’s flame.

What Kind of Alcohol Goes in an Alcohol Lamp?

The best alcohol for your spirit lamp is denatured alcohol or ethyl alcohol. Denatured alcohol is actually about 5% methanol, with the rest being ethyl alcohol. Ethyl alcohol is also known as grain alcohol. When it comes to alcohol for your spirit lamp, you can also use isopropyl alcohol as well.

No matter which alcohol you choose to use in your spirit lamp, make sure that it’s at least 90% alcohol for the most effective fuel.
