Thirium is a small Minecraft mod that adds a few new items to the game!
The main item is Thirium itself, crafted by combining glowstone dust and blue dye in a crafting table. With this Thirium item, you can make a block of Thirium, which can be used for decorational purposes. Thirium can also be combined with a water bottle in a brewing stand to make a new potion titled "Blue Blood", which provides a mixture of new boosts. The potion has a splashing & lingering version, as well as a tipped arrow!
If you're looking for something to do with all your leftover glowstone dust in your Minecraft world, this mod will give another use for it to make new decorations and enhance gameplay with the new potion.
