Glassential

Glassential is a mod by Lykrast, maintained by UpcraftLP on Fabric. It adds several types of glasses each with special properties, as well as a few items related to glass.

Despite the current Forge and Fabric versions having different version numbers, they both add exactly the same features. The only difference is that the Fabric version has a creative tab containing all blocks from the mod on top of them being in the Minecraft creative tabs.
