1.3g Fireworks tend to be more potent than 1.4g, but that’s not always the case. Many things influence what a firework 1.3g is. One is that if the burst charge or effect in a single tube contains more than 5% flash powder, then it becomes 1.3g. Rockets over 20g also automatically become 1.3g. In certain instances, a 30mm tube of 1.4g will be more potent than a 20mm tube of 1.3g based on the chemical makeup. So while most 1.3g products are more potent than usual, there’s a bit more to it.

Sometimes, delivering 1.3g fireworks can be a real issue. When delivering high quantities of 1.3g rockets, the driver will need to have an exclusive ADR license. Luckily, we have access to couriers which carry 1.3g safely and securely. We may also need to know when you are collecting as the storage of 1.3g rockets is also limited and regulated; so, if we know when you are collecting, we can make sure you have the exact amount for the time you receive your fireworks.
At Firework Crazy, we only work with the very best firework manufacturers. All of our products on our website are there because they only provide the exact bang mentioned on the packaging. So, have a browse knowing that the 1.3g products on our website are of high-quality and suited for all occasions.
Many people believe that all 1.3g fireworks are more potent than 1.4g fireworks, but this isn’t always the case. Different things can determine what makes a firework 1.3g or 1.4g, such as it’s size, the number of certain chemicals and also the packaging.
In some instances, 1.3g fireworks are more potent than their 1.4g fireworks because they contain a larger quantity of flash powder. Or, for example, in the case of rockets, anything that has more than 20 grams of powder is classified 1.3g. However, you can have poor quality 1.3g fireworks that are made with cheap components and chemicals that are nowhere near as good 1.4g fireworks that are constructed from high-quality ingredients and chemicals.
