Meanwhile, one of the zoo’s staff Tian Shuliao told the media that “this monkey is unlike other monkeys. This one knows how to use tools to break walnuts. When we feed walnuts to other monkeys, they only know to bite it. But it had never hit the glass before though. This is the first time. It’s toughened glass, so it would never have got out. After it happened, we picked up all the rocks and took away all its ‘weapons’.”

Tempered glass doesn't make it escape proof; the lamination does. Tempered glass can withstand harder blows, but it shatters into small pieces when it breaks. Sharp objects (like this stone) makes them easier to break, and even a small tap on the edge can make it explode (google prince Rupert's drop to see how it works)
This is also why tempered glass is used in car windows (as "safety glass"; it doesn't make long sharp "swords" that can impale you in an accident.
