Tough Glass
Tough Glass adds a glass block and a glass pane that pistons cannot move and that resist blasts better than regular glass, aimed at builders who want stronger walls.
What it does
The Tough Glass block has the blast resistance of obsidian and a hardness of 10, and it resists more force than regular glass. It cannot be pushed or pulled by pistons, and slime blocks cannot move it either. A diamond pickaxe is required to break the block, and it only drops itself when a Silk Touch tool breaks it, so broken pieces are not collected otherwise.
Tough Glass Pane is the companion block, with the same properties as the full block in a thinner form, like normal glass panes. The mod's advancement trigger was fixed so it no longer changes a player's inventory. It is published for Fabric and Quilt for 1.18.2 and 1.20.1, and the latest files target 1.20.1. A server running it needs every connecting player to have it too. The code is open source under the MIT License, and the source code and issue tracker are public.
Key features
Blast-resistant glass block
The block matches obsidian in blast resistance, so explosions do not break it quickly.
Piston immunity
Pistons and slime blocks cannot move the block, which keeps walls and displays in place.
Tough Glass Pane
A thin pane shares the block's properties and fits the same placement as normal glass panes.
Silk Touch drops
Only a Silk Touch tool collects the block intact, and mining requires a diamond pickaxe.
Compatibility
Latest build for each game version and loader.
This mod also publishes snapshot builds. Snapshots are not shown in the matrix.
Use cases
Protected builds
Walls and roofs made from the block resist explosions and cannot be shifted by pistons.
Piston-proof windows
Panes can divide a base into sections without a piston-driven mechanism breaking the view.
Who it’s for: Builders and server owners who want glass that holds up better than the vanilla block against explosions and piston mechanisms.
How it compares
Better Glass Panes is a Fabric-only client and server mod for 1.21.1 under the MIT License, so it targets a later version than Tough Glass. Translucent Glass is client-side only and open source under the GNU General Public License v3.0 only, with Fabric files for 1.20 – 26.2. Glass Item Frames supports Fabric and Quilt for 1.20.1 – 1.21.10 and is client and server under the MIT License, adding item frames rather than glass blocks.
