Blast-Proof Glass

Blast-Proof Glass is a block that is resistant to explosions. You can buy 12 Iron for 4 Glass. It cannot be blown up using TNT or fireballs.

Strategies

We recommend that you use the Blast-Proof Glass as the second-to-last layer (as in right under outer layer), with the last layer being something cheap such as wool, or clay if you have the iron. The purpose is to conceal your defense to other players, which makes it easier to defend your bed. When TNT or fireballs are used, the wool will get damaged but it will do barely any damage due to the glass behind it. Always repair the wool after it was blown up.

When you are in late-game, you can also use this to bridge, as irons are abundant, and this will make you fireball-proof.

However, it is vulnerable to tool and can be break very fast by any tool.
