Project X Thermochromic Quartz Heat Color Change (14mm Male)

Yellow sand is an imported mineral, which will change color when heated to a certain temperature， When we tested this product, we used a hydrogen-oxygen fire spray gun with a temperature of up to 1900 ° F to heat the bottom of the product. When the yellow sand inside changed to heat and changed color, the color of the sand would still turn yellow after cooling.If the sand turns black after use, we estimate that the temperature of the heating tool is not high enough. Many people directly use a lighter or torch to heat it. If the temperature is not high enough, it may cause the bottom quartz to turn black. We try No matter how many times it is heated, the sand turns yellow after cooling
