The 12 Field Hospital (U.S. Army) Color Changing Coffee Mug is a unique piece of military-themed drinkware, designed as a tribute to the 12th Field Artillery Regiment, a unit of the United States Army with a rich history dating back to the American Civil War. The mug features an intricate design that pays homage to the regiment's insignia and its storied past. The most striking aspect of this mug is its color-changing property. When hot liquid is added, the mug transitions from a neutral shade to the bold red, white, and blue colors of the U.S. Army. This drinkware piece is perfect for anyone who appreciates unique and cool military collectibles, as well as those with an affinity for American history or the U.S. Army.

The design of this coffee mug is based on the insignia of the 12th Field Artillery Regiment, which includes a shield adorned with the regiment's motto, "Fortis in Arduis" (Strong in Adversity). The mug's body is shaped like an artillery shell, further emphasizing its military theme. The color-changing technology used in this mug adds a touch of modernity to a design that celebrates tradition and resilience. This coffee mug makes an excellent gift for veterans, history enthusiasts, or anyone who appreciates unique and cool drinkware.

Color-changing ceramic mugs with a glossy finish, black exterior, and white interior. Available in one size: 11 oz (≈330 ml). Heat-reactive coating reveals your custom design when filled with hot liquid. BPA- and lead-free, with a comfortable C-handle.

This mug brings a playful twist to the daily coffee or tea ritual. At room temperature, it looks like a simple black mug with a glossy finish. But add a hot beverage, and your chosen design fades into view, showing vivid colors against the white interior.

The ceramic body is durable enough for repeated use, while the C-shaped handle balances comfort and grip. Printing uses sublimation techniques that fuse color into the heat-reactive surface for crisp results when the design appears.

  • Material: ceramic with glossy black exterior and white interior.
  • Size: one standard size, 11 oz (≈330 ml).
  • Finish: glossy glaze with heat-sensitive surface.
  • Printing: sublimation process produces crisp, vibrant colors.
  • Safety: BPA-free and lead-free, suitable for everyday drinks.
  • Effect: design is faintly visible when cold, fully revealed when hot.

Perfect as a novelty gift or a fun personal mug, the heat-reactive design makes coffee breaks more engaging. It works well for morning coffee, afternoon tea, or hot chocolate.

  1. Daily routine: fill with any hot beverage to reveal your chosen artwork.
  2. Gifting: the “magic” reveal makes it a memorable present for birthdays, holidays, or office exchanges.
  3. Office use: sparks conversation while still being practical for everyday drinks.

Note: for best results, avoid designs that rely heavily on deep black backgrounds, as they may blend with the mug’s surface when cold.

Unlike standard mugs, color-changing mugs require gentler care to preserve the heat-reactive coating. Hand-wash only — avoid the dishwasher and abrasive scrubbers, which can damage the finish and reduce the effect.

The mug is safe for short microwave use when heating liquids, but repeated high-heat cycles may shorten the lifespan of the coating. Always allow the mug to cool before washing.

Available in one classic size: 11 oz (approximately 330 ml). It’s large enough for most standard coffee makers and fits comfortably in most cabinets.
