Thermochromic glass
Northern Lights is a glass product that can change its appearance due to a change in temperature. Human touch, a change in the ambient air temperature, hot or cold water, or any relatively warm or cool source will trigger a thermochromic response. Northern Lights material may be designed in any size or thickness of glass, colors, as well as multiple activation temperatures. Moreover, the material’s base color may be matched to custom colors.
