Glass powder is the result of glass being crushed using a mill. Glass powder is commonly used to make electronic tapes along, and can also be used as an additive or filler for other electronic applications. Blinding is a huge problem that occurs when sieving glass powder due to the high density of the product. Glass powders can also have varying particle shape, which makes it difficult for some particles to fit through the hole opening. Lastly, agglomerations are very common with glass powder, which can cause the appearance of oversized particles.
