How do mugs change Colour with heat? A magic mug, also known as a heat changing mug, is a mug that changes colour when it is filled with a hot liquid. This effect is created by using thermochromic ink. Mugs are microwave safe; however, the design may fade over time due to the heat exposure from the extreme heat of the microwave.

Discover our range of heat change mugs! With this Dragon Ball Z magic mug by House of Spells, bring up the energy halo of Goku and call the dragon Shenron by pouring a hot beverage in the mug. Your mug changes dramatically when you run your hot chocolate, tea, or coffee every morning.
