Glow in the dark powder tumbler, as a non-toxic, harmless, and environmentally friendly pigment, can be mixed with any colorless, transparent, neutral medium, such as paint, ink, rubber silicone, plastic resin, glass, ceramics, and more. Among them, the glow in the dark tumblers has become a popular and novel product in recent years. It can absorb light from lamps or sunlight and emit a luminous glow in yellow-green, blue-green, or sky blue colors at night. Whether as a gift or for personal use, it is truly pleasing to the eye.

Glow in the dark tumblers is made by mixing glow in the dark powder with glass powder and firing it in a furnace. Generally, there are two effects: the starry effect and the overall glow effect. The starry effect uses large particles of glow in the dark powder, which glows like a starry sky in the dark environment; the overall glow effect uses smaller particle size of glow in the dark powder, and the effect is that the whole tumbler glows due to the large distribution area of the pigment.

The production of glow in the dark tumblers is not complicated. It is made by mixing glow in the dark pigment with glass powder and firing it in a kiln. However, customers need to experiment on their own because each customer’s kiln conditions and temperature testing methods are different. In addition, there are some colors and particles that are relatively resistant to burning, but these need to be selected based on the tumbler manufacturing process and customer preferences. Customers need to test with samples to see if they are satisfied with the final product before making a decision.

In summary, to produce glow in the dark tumblers with high temperature heating, we always recommend: the lower the firing temperature the better, and the shorter the firing time the better, so that the success rate of making glow in the dark tumblers is higher.
