The Actual physical conduct of silicate magmas is dominated by the silica ingredient. Silicon ions in lava strongly bind to four oxygen ions inside a tetrahedral arrangement. If an oxygen ion is lava bound to two silicon ions during the melt, it is actually described as a bridging oxygen, and lava with a lot of clumps or chains of silicon ions connected by bridging oxygen ions is referred to as partly polymerized.
