About Your Custom Heat Changing Mug

Magic mugs come with either a navy blue or black base color that covers your design. Only when filled with hot water will your image be revealed, so when it's not in use your mug will appear either blue or black. When you're designing your custom color-changing mug, view your creation as both hot & cold to get a clear idea of how it'll look aesthetically in its different forms. Made from solid white ceramic, they are durable, contemporary mugs.

How your Color Changing Mugs are Printed & Made

We print your bespoke designs onto a special layer that reacts to heat, changing from the base color to white when filled with your hot drink of choice. Only the body of the mug has this layer, so your handle remains blue or black. We package them up in their cold state so all you will see is either black or blue when it first arrives, ideal if you're creating one for a surprise. As the heat sensitive mug is activated, the reveal starts at the bottom and the base color magically starts to vanish. Please note that the blue or black base color isn't completely opaque, and the outline of your design might come through slightly, more so if you select blue.

Design Tips

When you make your own heat changing mug, your unique design wraps around the body of the mug, only leaving a small gap when it reaches the handle. We don't print on the handle as this could distort your beautiful design. The full height is covered leaving almost no white space at the top or bottom of your custom heat sensitive mug. A clever idea would be to print a secret message with the first word placed at the bottom, that way the sentence can be read as the custom heat-activated mug works its magic. 

As the outline can be seen slightly, we'd suggest opting for designs that feature lighter, more subtle colors on your personalized heat changing mug. However, it's only slightly visible and the effect isn't diminished because of this. 

If you're in the wedding business, the custom color changing mug is a fun addition to your product range, as they can be used for proposals, maid of honor requests or hen party reveals. Simply create color changing mugs with various slogans and quotes and add them to your range. You can also use them for hospitality as they'd be a popular talking point among guests. Print a special greeting to guests welcoming them to the event, or use them creatively for a competition whereby only one customizable heat changing mug has the winning symbol.

With the custom heat changing mug you get 2 in 1. When the custom color changing mugs are cold, your kitchen cupboards are neat, tidy and uniform, but when you use them, all the family can experience a different design. Sometimes, certain mugs get overused and others are underused, but as these all look the same when cold, you don't know what you'll get.

How do heat sensitive mugs work?

We print your design onto a special layer that reacts when hot liquid is poured in. Once activated, it slowly disappears revealing your design.

Is my design totally concealed?

You choose from either a blue or black base tone. Your design is slightly visible under both colors, but less so with the black base.

Can I print on the handles too?

The heat activation only occurs on the body of the mug, so your handles will remain either blue or black, depending on the selected base color.
