These common snowflakes are thin, plate-like crystals with six broad arms that form a star-like shape.

Layers of material which work as filters, electrodes, transistors and the liquid crystal itself are deposited onto a thin glass plate to form a sandwich that is covered with another pane of glass.

Corrosion on Aluminum vessels is also generally in the form of localized pitting to the hull plate, rudders, bilge keels and particularly in way of weld seams.
