The thickness of the glitter determines the quantity and weight. For example, the use of two different thickness of the glitter, the total weight of 25 kg, the thickness of 25 um of the glitter can cover the area of 100 m², the thickness of 50 um due to double the thickness, resulting in the coverage of 50 m², under the same weight, the thin material than the thick can cover the area will be larger. (The effect of glitter thickness is particularly prominent in the composite leather industry). The weight of the glitter (the thicker it is, the heavier it is) also affects how quickly it sinks in the epoxy, and thinner glitter is more reflective and brighter due to its lighter texture.
