What is Scratch Paper?
Scratch paper, also known as paper scratch paper or dry-erase paper, is a unique and versatile writing material that has been a staple in many classrooms and homes for decades. But what exactly is scratch paper, and how does it work its magic?
What is Scratch Paper Made Of?
Scratch paper is made from a mixture of alkaline chemicals, such as potassium nitrate, potassium chlorate, and sodium nitrite, which are dissolved in a mixture of water and pulp. The pulp is then dried and pressed into a sheet of paper, which is coated with a thin layer of a glass surface treatment.
How Does Scratch Paper Work?
When scratch paper is exposed to moisture, the alkaline chemicals in the mixture react with the water and pulp to release a precipitate of tiny bubbles. These bubbles form the adhesive layer on the surface of the paper, allowing users to write and erase on it easily.
