Several mods, such as Extra Utilities, add a bunch of cool glasses to your game. Like glass that you can see through but blocks light or glass that emits light.
Have you ever wanted to get that cool stuff, but without all the overhead of putting a major content mod in your modpack? Well look no further than Glassential.
It adds the following glasses, for a total of 32 with the combinations:
Before version 2.0.0 (in Minecraft 1.20.1), there only was Luminous, Redstone, Ghostly, Ethereal, Reverse Ethereal, Tinted Ethereal, and Tinted Reverse Ethereal.
In Minecraft 1.16.5 and below, there is also Dark Glass, which is like modern vanilla Tinted Glass.
Glasses are also all fully compatible with ConnectedTexturesMod (which I highly recommend).
