How the heat reveal works
This heat changing mug starts out dark. Pour in hot coffee or tea and the thermochromic ink reacts to the warmth, shifting the printed alphabet and string lights from dark to full color. As the drink cools, the artwork gradually fades back, ready to surprise you again with the next cup.
There is nothing to charge or switch on. The color change runs on the heat of your drink alone, with no batteries, LEDs or wiring, and the artwork wraps a full 360 degrees so the letters show from every angle on your desk or kitchen counter.
Size, feel and everyday care
The ceramic body has a smooth, comfortable handle and holds approximately 11 to 12 oz (330 to 350 ml), a regular everyday size for a morning coffee or an evening tea. It makes a fun gift for anyone who loves a small moment of surprise in their daily routine.
To keep the color change vivid, hand wash the mug and warm your drink before pouring it in, keeping the mug itself out of the microwave and dishwasher.

Frequently Asked Questions
How does a heat changing mug work?
The mug is printed with thermochromic ink that reacts to temperature. When you pour in a hot drink, the alphabet and string-light artwork shifts from dark to color, then gradually fades back as the mug cools. It needs no batteries, LEDs or wiring, only the warmth of your coffee or tea.
Can this color changing mug go in the microwave or dishwasher?
This mug is hand wash only. Warm your coffee or tea separately, pour it in, and watch the alphabet and string lights appear, then wash the mug by hand afterward. Keeping it out of the microwave and dishwasher preserves the heat-reactive thermochromic ink coating, so the reveal stays ready for your next cup.
Is the color-changing ink safe to use with hot drinks?
Yes. The mug has a ceramic construction, and its color-changing ink reacts safely to temperature. Simply pour in hot coffee or tea as you normally would, and the printed design responds to the heat by shifting from dark to full color before fading back as it cools.
How much does the mug hold?
It holds approximately 11 to 12 oz, or 330 to 350 ml. That is a regular everyday size for a cup of coffee or tea, with a smooth, comfortable handle and artwork wrapped a full 360 degrees around the ceramic body so the design shows from every side.
