Compare these GBMF melt fluidity balls. The FZ556 is completely matte compared to the others. It is melting as well as some of them, but they are all glossy. The matteness is a product of the chemistry. The extremely high zinc content, coupled with low silica and alumina, are crystallizing it on cool down.
