We can give you all the Minecraft tips and tricks there are to find rare materials like diamonds, villages, and everything about the various biomes, but you will need a different approach to get glass. Just like making a bed, you will need to rely on your crafting skills to make this item. Here's the full recipe for glass.
How to make glass
The materials you’ll need to make glass are relatively easy to come by, and you might even have them in your inventory already. To make glass in Minecraft, you’ll need some sand, a furnace, and a fuel source for it.
Step 1: Interact with your furnace.
Step 2: Put a fuel source like wood or charcoal in the bottom square.
Step 3: Put your sand in the top square.
Step 4: Wait for the furnace to cook the sand into glass and remove it from the output square.
Glass is one of the main ingredients in many useful materials in Minecraft. You can do so much with it, from making bottles and window panes to creating beautiful stained glass. One of the more basic creations are panes, which are made by combining six glass blocks at a crafting table. Make sure you fill the top two rows while leaving the bottom row blank. Use the image above for reference. Adding a pane is essential to making a window, and doing so will give your creation much more detail.
You can also combine eight glass blocks with dye to stain it and give it some color. There are numerous dyes you can use, both on glass blocks or on panes. When staining blocks at a crafting table, make sure you use eight glass blocks, with the middle square blank — that’s where you’ll place the dye. You might have some dye on you if you’re a frequent player, but otherwise, you’ll need to craft it.
