Glass Wall

Glass Walls are an essentially transparent wall, and resemble Glass blocks. Prior to the 1.1 patch, Glass was only able to be placed like any other block, so it was not possible to place it in the background. Before Glass Walls were introduced, you could make holes in the background of your Home, but the size of those were limited due to housing requirements. Now, with the addition of Glass Walls, it is possible to make larger "windows" that can produce safe, natural light. You can also use glass walls to construct a greenhouse for gardening in. You can place them "contiguously" or in a paned-glass pattern depending on preferred aesthetics.
