The best fireworks are typically categorized as "professional-grade" or "display-grade" fireworks, which are larger and designed for use in organized fireworks displays. These fireworks can include aerial shells, multi-shot cakes, and larger-scale pyrotechnic devices that produce impressive and spectacular effects. They are not available for consumer purchase and require specialized training and licensing to handle and operate. The most powerful consumer fireworks are Category F3 fireworks using 1.3G explosive effects.
In general, consumer fireworks are categorized as either 1.3g or 1.4g. While 1.3g fireworks tend to contain a higher amount of flash powder, resulting in louder and more substantial bursts, it's important to note that the classification alone doesn't always dictate the level of spectacular effects, this can vary on type of effect and bore size. Many 1.4g fireworks can also deliver equally impressive displays.
