The pigment particles are conventionally manufactured by wet or dry milling in ball mills from melt atomized metal powder, which only results in flat particle geometries [4]. Depending on the particle size, aluminum powder is pyrophorous [5,6], which is why aluminum pigments are usually milled in wet conditions [3].

August 29, 2016. It's hard to prove that glass sparks, except finding a reference to it's piezoelectric properties. But that's only part of the problem. Glass is brittle and will flake off, and ground glass is a well-known friction-increasing additive. And either way it's too hard, increasing the risk of impact ignition.
