When you are smelting your own fireworks, we will be using a gadget called Launch Tube. But how does this gadget actually work?
Genshin Impact How To Use Launch Tube Gadget
So to start the process, go to the Gadgets section and click on the Launch Tube, then go to the Smelt Fireworks option.
Next, select the option you want to smelt, and then the smelt section will open with the color, size, and height of the fireworks.
Here you can choose different types of techniques to improve the quality of smelting such as Tactile Sensitivity, Nitpicker, Decisive Boldness, Meticulousnesses, and many other smelting techniques.
Basically for every smelt, you need to make a combination of different smelt techniques to get premium quality of the firework.
Next, click single smelt until you reach the red highlighted bar. Do this for the color, size, and height parameters, and finally click Complete Smelting.
Pretty simple, right? Remember that you just need to find the right combination for a premium quality smelt.
