Lamina - (thin glass)
by LibertyMouse
Lamina adds thin glass blocks for Fabric on 1.21.1, with a copper-laid look inspired by ContentSMP and a rim-only design.
What it does
Lamina adds thin glass blocks that are only visible at their rims, so each piece reads as a slim pane instead of a full block. Its connecting texture is faked, so adjacent pieces appear to join along their edges even though each block is standalone. The copper-laid glass variant takes its inspiration from the ContentSMP look.
The mod is commonly used to build a slim aquarium, where the thin rims keep the view clear and the walls stay unobtrusive. Crafting is done through a recipe added by the mod. The server and every player need the mod installed. Files are published for Fabric only, for 1.21.1, with 1.0 as the latest file released on 2026-06-23 under All rights reserved, which means the code is not open source.
The mod is one of 3116 Decoration mods with Fabric files for 1.21.1, and it is a single-version release for that game version alone.
Key features
Thin glass blocks
Glass pieces that show only their rims, giving a slim, framed appearance to walls and panels.
Faked connecting texture
Adjacent pieces appear joined along their edges, because the rim texture is drawn to suggest a continuous pane.
Copper-laid variant
A copper-laid glass style inspired by ContentSMP adds a metallic accent to the thin glass blocks.
Aquarium building
The thin rims let builders make a clean, low-profile glass wall for an aquarium.
