Materials used to make terrestrial globes
Terrestrial globes are a popular way to represent the Earth’s surface. They are not only educational tools but also decorative items. But have you ever wondered what materials are used to make these globes? In this article, we will explore the different materials that are used to create terrestrial globes.
Paper
One of the most common materials used to make terrestrial globes is paper. Paper globes are typically made from sturdy cardboard or thick paper. The globe is printed on the flat sheet of paper, then cut, assembled, and glued together to form the three-dimensional shape. Paper globes are lightweight, affordable, and easy to produce, making them a popular choice for schools and classrooms.
Plastic
Plastic is another popular material used in the production of terrestrial globes. Plastic globes are made through the process of injection molding, where molten plastic is injected into a mold and left to cool and solidify. Plastic globes are durable, lightweight, and can withstand rough handling. They are often used in children’s playrooms or as outdoor decorations due to their weather resistance. However, plastic globes may lack the same level of detail and accuracy as other materials.
Acrylic
Acrylic is a type of plastic that is widely used in the production of high-quality terrestrial globes. Acrylic globes are made by heating the material until it reaches a molten state and then spinning it into a globe-shaped mold. The spinning motion creates a smooth and even surface, resulting in a crystal-clear globe. Acrylic globes are known for their exceptional clarity and detail, making them a popular choice for museums and collectors.
Metal
Metal globes are the epitome of elegance and durability. These globes are made by casting or spinning metal, such as bronze or stainless steel, into the shape of a globe. Metal globes are usually handcrafted and meticulously engraved to depict the Earth’s features accurately. They are often used as decorative pieces in offices, libraries, or high-end homes. Metal globes may be more expensive compared to other materials, but they are built to last and can be considered as investment pieces.
