This banger is a very different quartz banger that you're used to. They come with heat reactive color changing crystals called thermochromatic. This helps because it can give you a visual experience of your temperature.
Using a torch, heat your banger until the crystals change color. Keep the torch about an inch away from the banger and heat each side for about 15-20 seconds. Wait another 15-20 seconds for it to cool down.
