Color-changing mug is also called magic mug. When hot or cold water is poured into the mug, there will be a color change in the mug body. Before changing color, the original color of the mug body may be black, red, yellow, green, blue, brown, purple, light blue, light yellow, light green, light red, light purple, pink, etc.
The dot effect can also be designed as the surface of a color-changing mug. Ceramic color changing mugs and glass color changing mugs have three different color changing modes, namely, heat discoloration, cold discoloration and discoloration when exposed to water.
Color changing principle
If the temperature of the heat discoloration mug is higher than 40℃ or the temperature of the cold discoloration mug is lower than 20℃, its color will change. However, there are still few color-changing mugs that discolor when exposed to water. The temperature sensing material of the color changing mug is printed on the mug body. Its material used is temperature sensitive, high temperature resistant, nontoxic, lead-free and chromium-free, with maximum withstanding temperature 320℃ and its metal content can meet European standards. According to the plan of the design draft, film making, plate making, printing, drying, baking and packaging are carried out.
Nowadays, the material mugs used are processed into color changing mugs with mainly one of these three methods: 1. Direct printing; 2. Water transfer printing; 3. Heat transfer printing. These three technologies are used for processing.
- Direct printing
Direct printing refers to printing directly on mugs with a roll printing machine, which is somewhat difficult. Rolling printing machines in ordinary factories can only print one to three colors. If there is a high requirement for set positions and many colors, there is nothing could be done. However, powerful factories can overprint as many as 20 colors without blocking. This technology only applies to small batch production and with it, the efficiency is very low. Besides, with this technology, only color blocks can be printed and photo effects are difficult to print.
The full color-changing mug is a legend among the color-changing mugs (Full color-changing mug is a mug that changes color all over except the mug handle). The full color-changing mug was first developed by a British company and applied for a technical patent regarding European and American markets. In 2004, Beijing US-funded company Meikeda introduced the full color-changing mugs to explore the Chinese market. It is said that the company had to pay a high royalty regarding European and American market to British company every year. At that time, the technology of full color-changing products was already very mature. The production of high-gloss full color-changing mugs had high technical requirements for workers, coupled with the imported raw materials, so the price was relatively high. Although many factories could be able to produce full color-changing mugs, they must use expensive professional equipment and employ highly skilled production workers to produce high-quality full color-changing mugs with a certain product qualification rate….
Ceramics are the general term for pottery and porcelain. Traditionally, ceramics refer to all artificial industrial products made of inorganic nonmetallic minerals such as clay. It includes various products made of clay or mixture containing clay through mixing, shaping and calcining. The roughest earthenware and the finest fine pottery and porcelain are all ceramics. The main raw materials of ceramics are silicate minerals (such as clay, feldspar, quartz) from nature, so they are classified as “silicate industry” together with industries such as glass, cement, enamel and refractory materials.
