This is the official Curse page for Fragile Glass and Thin Ice, by FredTargaryen.


This mod adds (separate) fragile versions of glass blocks and panes, which are made of sugar and smash gratuitously if something hits them fast enough. It's great for adventure maps, videos, pranks, and as a quick, realistic glass substitute. From version 1.8.5 onwards, mod makers can use the Capability system to make their own entities able to break fragile blocks, or make their own blocks fragile.


Versions 1.7.10-1.4 and 1.8-1.2 introduce Thin Ice, which can catch you off guard on frozen water.

Version 1.8.5 introduces Weak Stone, which generates above drops and crumbles if you step on it.

Generation of both blocks is fully configurable in ftfragileglass.cfg. By default, Thin Ice is enabled but Weak Stone is disabled (as it is more dangerous).


NB. Fragile Glass blocks are separate from vanilla Glass blocks and never replace them in the world.

However, when each world is created, if enabled, patches of Thin Ice/Weak Stone replace vanilla Ice and Stone in the same place.
