Ultimate Glass

Ultimate Glass makes glass panes much more flexible for building.

Place panes along block edges, mount them horizontally, rotate them after placement, make proper glass corners, add wooden frames, and even combine glass with stairs and slabs.

It stays close to the vanilla look — just with panes that are much less annoying to build with.

Tempered Glass Panes

Smelt vanilla glass panes in a furnace or blast furnace to create Tempered Glass Panes.

When placed normally, the pane snaps to the closest edge of the block face you clicked.

Need more control? Shift + right-click places it directly against the clicked face instead.

Tempered panes can be:

• placed vertically or horizontally
• attached to different block edges
• waterlogged
• connected into clean corners
• rotated after placement

Matching panes also connect seamlessly, without thick borders breaking up larger windows (configurable in mod menu).

Clear, stained and tinted glass are all supported.

Wooden frames

Combine a Tempered Glass Pane with any plank to add a wooden frame.

All vanilla wood types work, and modded planks are supported automatically. Frames made from modded wood use that plank's texture, so they fit naturally with the rest of the wood set.

Glazier’s Tools

Glazier's Tools let you adjust glass without constantly breaking and replacing it.

• Copper — rotates panes
• Iron — rotates panes and switches between edge and centered placement
• Diamond — same controls, plus faster glass breaking

The rotation-axis key can be changed in Controls and defaults to V.

Experimental stair and slab glass

Tempered glass can also share the same block space with stairs and slabs, making things like angled windows and more unusual shapes possible.

These combined blocks still support rotation and edge/center switching with Glazier's Tools.

This feature is currently experimental and disabled by default. You can enable it through Mod Menu.

Configuration

Mod Menu is optional, but adds settings for things such as seamless connections, experimental stair/slab glass, pane drops, reverse crafting and Glazier's Tool recipes.

Gameplay-related settings are synchronized by the server.

Multiplayer

Ultimate Glass must be installed on both the server and connecting clients when playing multiplayer.
