Glass Wall

A Glass Wall is the un-official name given to a new background wall seen in a picture supplied by Tiy on the terrariaonline forums.

In this picture, you can also notice that the Glass Wall meets with the wood wall nicely (along with the Stone Wall, connecting smoothly. This may only be the case for Glass Walls and Stone Walls, but it is currently unknown.
