This Thermochromic Banger has a special color-changing sand inside. The sand is a bright yellow when cool, but as its temperature rises it will change through warm colors until it turns a brilliant red! This banger heats up just like any other, but you can see the temp that works for you by deciding what color works best for you. If you already know you like a banger at 700 degrees, then first use a non-contact infrared thermometer to scan the banger until you reach that desired temp and take note of the color. From then on you will know what color to look for in the sand, and be able to know if you've gone too hot or aren't quite there yet!
Pure Quartz Glass
This banger is made from 100% Quartz glass, the best at dispersing heat evenly and keeping it retained. The sand inside will not interfere with your sessions, only remain in place and let you know the heat of the banger. Once the optimal temperature is reached, signaled by the color of the sand.
