"Washington, D.C. Officers of the U.S. Treasury Battalion; Incomplete Washington Monument During the U.S. Civil War" This historical image depicts a gathering of officers from the U.S. Treasury Battalion against the backdrop of an incomplete Washington Monument, during the United States Civil War (1861-1865). The U.S. Treasury Battalion was a military unit responsible for guarding government buildings and facilities within Washington, D.C. During this period of conflict, the city served as both the Confederate and Union capital at different times. The Washington Monument, initially erected to honor George Washington, the first President of the United States, remains unfinished in this image. Construction on the monument commenced in 1848 but was halted due to funding issues several years later. Work resumed after the Civil War's end and was finally completed in 1884. This photograph serves as a snapshot of Washington, D.C.'s tumultuous history during one of the nation's most divisive periods, showcasing both the military presence within the city and the progression of the capital's iconic landmarks. The image does not indicate the specific year it was taken, but it falls within the timeframe of the American Civil War.

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.
