This bowl is wider than standard bowls. A wide bowl enables you to move the charcoal around on the foil. This is especially useful when the molasses starts to overheat you can simply move the charcoal over to the other side instead of having to take it off and stop smoking. 

You may also find with a narrower bowl you always have some tobacco left towards the bottom when its time to change the tobacco. The clean large holes also help draw the smoke through easier.

The base area is flat on this bowl rather than being curved, giving a more equal spread and depth to the tobacco. Saudi Ultra Wide Bowl
