Glass

"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.

Glass panes can also generate in villages at any house.

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

From trading
Journeyman-level librarian villagers have a 50% chance to sell 3 glass for 1 emerald.

Journeyman-level librarian villagers have a $2/3$ chance to sell 4 glass for 1 emerald.

Info
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. $$, it transmits redstone signals up, not down. Otherwise, glass in redstone circuits is functionally the same as an upside-down slab.
