What's the aluminum foil?
To put it simply, it is ultra-thin aluminum sheet.
As a kind of decoration, if you make handicraft by yourself, it can broaden ideas, for example, it can serve as filler right hardness when making cross-stitch card pocket. Besides, it can also be used as cooking material, for example, you can wrap the chicken wings with aluminum foil after dipping enough sauce, and then roast the wings after you make sure that the oven can heat metal material.
Aluminum foil is a kind of thermoprinting material made by calendaring aluminum into sheet. Since its thermoprinting effect is similar to that of silver foil, it is also called fake silver foil. As aluminum is soft and ductile with silvery luster, aluminum foil sheet can be made by mounting calendered aluminum sheet on the offset paper with sodium silicate, which can be used to print. But the color of aluminum foil will gradually become dark as it is easy to be oxidized and it fade due to friction and touching, so it is not applicable to the thermoprint of book covers for permanent preservation.
