About Heat Changing Mug
Product specifications sourced from our UK print partners.
- Supply a PNG or PDF at 300 DPI, sized to the wrap template for this mug
- Request the free mug template — the printable wrap stops short of the handle on both sides
- Keep text and logos 10mm inside the top and bottom edges of the print area
- Full-bleed wraps need 3mm extra on all sides; the join sits behind the handle
- Dye sublimation prints no white — unprinted areas show the mug colour
- On black and coloured mugs, pale tones sublimate darker; high-contrast artwork works best
- 11oz black ceramic mug with heat-reactive glaze
- Turns from black to white when filled with a hot drink, revealing your design
- Dishwasher and microwave safe
- 95mm tall × 82mm diameter
- Print area 200 × 85mm — near full wrap
A heat-changing mug hides your design until hot liquid is poured in, at which point the black coating clears and the print appears. It is a novelty, and it works — recipients almost always show someone else.
Use it where the reveal is the joke or the message: a punchline, a before-and-after, a hidden offer or a logo emerging from a blank surface.
Hand wash only. The thermochromic coating is not dishwasher safe and will fade with repeated hot cycles.

Heat Changing Mug buying guide
Written by our studio team — what to choose, and what usually goes wrong.
- The mug is matt black when cold — light or white artwork gives the strongest reveal.
- Simple, high-contrast graphics reveal best; fine photographic detail is lost against the coating.
- Leave a 10mm clear margin at the handle and around the rim and base.
