NOTE: Since Mekanism V9, this block no longer exists and is thus replaced by Structural Glass. You can use Structural Glass if you want to add glass onto any Mekanism multiblocks walls (not frames), with the exception of Fusion Reactors and Fission Reactors.
Along with the Dynamic Valve and Dynamic Tank, Dynamic Glass makes up the multiblock that is the Dynamic Tank, a fluid storage structure that can hold a large amount of a single type of fluid. Dynamic Glass serves as a window into a Dynamic Tank. It can also be used as a purely decorative block.
