Most people don't know the difference between a tea kettle and a teapot. They find it confusing as both items look similar. Although they have similarities in terms of design, they are different when it is about their building-materials and working mechanism. Generally, tea kettles are made to tolerate high temperatures; in essence, these tools withstand direct heat for heating water. On the contrary, teapots are built to house heated water and to make tea. That's why they feature glass, porcelain, or ceramic. In summary, people use a tea kettle to boil water and then pour water into a teapot. After that, they pour tea leaves inside the teapot and prepare the tea.
