	“	Glass, you see, can't be broken with regular tools in Minecraft. Well, not without it shattering into a million tiny, invisible shards. Any experienced builder will always cook up more glass than they need for this exact reason - the tiniest slip and you'll have to make a lengthy trip back to the desert for more sand.	„
		— Duncan Geere

Glass is a decorative, fully transparent solid block that can be dyed into stained glass.

Natural generation

Magenta stained glass naturally generates as windows in end cities.

A secret room containing glass can be found inside woodland mansions.

Obtaining

Glass drops itself only if it is broken with a tool enchanted with Silk Touch; otherwise, it drops nothing.

Trading

Villager librarians offer to trade 3 to 5 glass for 1 emerald as part of their tier 3 trades.‌^{[Legacy Console Edition only]}

Journeyman-level librarian villagers have a 50% chance to sell 3 glass for 1 emerald.‌^{[Bedrock Edition only]}

Journeyman-level librarian villagers have a ²⁄₃ chance to sell 4 glass for 1 emerald.‌^{[Java Edition only]}

Usage

Torches and redstone torches can be placed on top of glass, but not attached to their sides.‌^{[Legacy Console Edition only]}

Glass blocks adjacent to other glass blocks are invisible when viewed through glass.

As a solid block, zombie reinforcements can spawn on top of glass, resulting in unexpected zombies "sneaking into" an otherwise secure area of a structure.

Redstone dust and components can be placed on glass but cannot power glass. Glass can't cut vertical redstone. Vertical redstone can be placed on glass but will only transmit redstone signal up, not down. Glass in redstone circuits is functionally the same as an upside down slab.
