TANGLONG Color-Changing Sublimation Coffee Mugs 11oz Pack of 12 — Heat‑Sensitive Glossy Black Coating

TANGLONG 11oz color-changing sublimation mugs are ceramic heat-sensitive cups that reveal a printed image or design when filled with hot liquid.

These TANGLONG magic mugs come as a set of 12 eleven-ounce ceramic blanks with a glossy black, heat-activated coating prepared for full-surface sublimation. Cold, the mugs appear solid black; pour in a hot beverage and the coated layer becomes transparent to reveal your custom transfer underneath. Each piece is treated for durable prints and intended for everyday use.

How does the color change process work?

Each mug is finished with a temperature-sensitive coating that becomes translucent when heated. That reveals whatever sublimation transfer you have pressed onto the ceramic substrate beneath the coating. The effect repeats with every heat/cool cycle, delivering a reliable reveal each time.

• Glossy black thermochromic coating conceals the print when cold
• Hot liquid or microwave exposure triggers the reveal
• Sublimation transfers bond beneath the coating for consistent results
• Designed to cycle through many heat changes without losing the effect

Are these mugs safe and suitable for sublimation printing?

TANGLONG mugs are ceramic blanks coated and cured at high temperature to accept dye-sublimation inks. The coating is manufactured to be lead- and chrome-free, and it’s intended to retain vibrancy after transfer. Proper heat and timing during pressing ensures best adhesion and lasting prints.

• High-temperature cured ceramic base for stable sublimation results
• Lead-free, chrome-free coating for safer everyday use
• Requires slightly longer press times to protect the thermochromic finish
• Finish designed to resist fading under typical dishwasher and microwave use

What are the size and practical uses of these 11oz mugs?

Each mug holds approximately 11 ounces and measures roughly 3.8 inches tall and 3.2 inches wide, a familiar size for coffee, tea, and hot cocoa. The set of twelve makes them convenient for events, small retail batches, gifts, or personalized orders for family and friends.

• 11oz capacity — good for standard hot beverages or small soups
• Compact dimensions suitable for most mug sleeves and cup holders
• Pack of 12 supports parties, classrooms, or small business runs
• Reusable design: effect repeats each time the mug is heated

How should I care for printed TANGLONG magic mugs so designs last?

To preserve the thermochromic coating and the sublimation print, follow recommended press settings and allow the proper transfer time. Although treated for dishwasher and microwave tolerance, gentler washing and standard handling will extend the life of vivid colors and the reveal effect.

• Follow longer heat-transfer times as recommended for coated mugs
• Dishwasher-safe but hand washing extends vibrancy
• Avoid abrasive cleaners or rough scrubbing on the printed area
• Store away from prolonged direct sunlight when not in use
