Yes, wax paper melts using an iron. Wax paper is coated with a thin layer of wax, which melts when exposed to heat. This can be a handy trick for tasks like sealing envelopes or creating custom shapes for crafts. However, it's important to use caution when ironing wax paper, as the melted wax can be flammable and may damage your iron. To avoid any accidents, it's best to place a protective layer, such as a sheet of parchment paper, between the wax paper and the iron.
