In daily study, work, and life, the most familiar thing to everyone is composition. With the help of composition, people can achieve the purpose of cultural exchange. I believe many people will find it difficult to write essays. Below is my tea cup essay that I compiled for your reference. I hope it can help friends in need.

Beside my bedside there is a delicate little tea cup, which was given to me by my cousin on my birthday. Because it is very beautiful and changes color when exposed to heat, I often use it to hold water for drinking. . Since it is so beautiful, let me introduce it.

It is an insulated color-changing cup. When not changing color, the whole body is light blue, but when exposed to heat, it turns purple. There is a crown engraved on the cup, and next to it is a scepter. Just below the rim of the cup is a golden lace surrounding the cup, and there is also a golden lace around the bottom of the cup. There are many types of color-changing cups on the market. I heard that ceramic color-changing cups and glass color-changing cups are divided into heat color-changing, cold color-changing and water-changing. The color of the thermochromic cup changes when the temperature is above 40℃, and the color of the cold color cup changes when the temperature is below 20℃. Discoloration when exposed to water is not yet popular. Their principle is: temperature-sensitive materials are printed on the cup body. The materials used are heat-sensitive materials, resistant to high temperatures of 320°C, non-toxic, lead-free, and chromium-free, and can all meet European standards. Carry out sheet production, plate making, printing, drying, baking, and then packaging according to the design plan of the design draft.

I think our life today is great, and technology is developing faster and faster. We would like to thank scientists for creating so many convenient and fast things for us.
