Reinforced Glass is a type of glass Block that is very valuable, due to the fact that it is completely see-through, and it cannot be broken by any dinosaur.
Reinforced Glass is a type of completely transparent glass, with tan borders around the top and bottom. Much like Ancient Glass, multiple blocks of Reinforced Glass placed side by side will cause their borders to merge, creating an almost completely see through surface.
It is most commonly used to keep strong predators such as Tyrannosaurus in, since it has the same strength value of iron. It's also very useful for base defence because of its strength and transparency.
It is made by smelting Dense Sand in a furnace.
