There are several types of hookahs, but most users will prefer to use coals. Hexagonal-shaped coals tend to produce the most ash. They are also more likely to roll, but using a diffuser can mitigate this problem. Hexagonal-shaped coals are often made from natural coconut husk. However, their composition varies from brand to brand.

When using coals, it is best to use a bowl that is completely sealed. Only the top of the bowl should have an air entrance, since it helps regulate the heat of the coals. Make sure to return the coals to the same spot on the bowl when finished.

If you are new to using coals, a quick-light charcoal is recommended. If you’re in a hurry, a cigarette lighter or a torch can be used to ignite the coals. Once the coals are lit, they will stay lit for about a minute or two. These coals will not give you the best taste, but they will be convenient if you’re only planning a short hookah session.

Coals can affect the length and quality of a smoke session, so it’s important to understand how to light them correctly. Quick-light coals are most commonly used by beginners, and are made with a chemical accelerant that helps light them quickly. These coals can produce a chemical odor, but burn much faster than natural coals.
