My idea is to add windows and other glass related objects which could be used in game for decoration and other uses.
To make glass, you will need 6 sand. Then, you need to put the sand in a furnace. You will now have crafted glass! Glass will come in the form of a semi-transparant whitish block. You could use glass in many different ways.
To make a window, you will need 4 glass and 4 sticks. You put the ingredients in a Workbench, and viola! You’ve just created a window!
Windows will come in a 2x2 glass block with wood bordering the outside of the block.
Those are all my ideas related to glass. I know he list is not big, but hey!
Thank you for your time!
