What is Glitter powder? Glitter is a very common product that is used from a variety of industries including art, coatings, pigments, and effects. Screening glitter is one of the most difficult processes in the world depending on the size of the powder. Glitter, by nature, is extremely lightweight and has the tendency to “float” inside the machine. Glitter is typically angular in shape and the misshapen nature of the particles can make the jagged ones very difficult to fit through the screen mesh. Sieving glitter needs to be done very slowly as it can plate up on the screen and cause blinding to occur.
