1 . 4G fireworks

Firework are classified for transportation and storage under the UN default scheme and in general fireworks that are classified as 1.4G tend to be less powerful than the 1.3G fireworks which makes them ideal for smaller gardens.  Other factors such as size, type and even the chemical composition of a firework as an impact on its performance so there are many 1.4G fireworks that have a good size burst and can even be loud as well.
