@theqmagnet There's actually some consistency here. Any block that is a compact version of a raw material will use the format "Block of X", x being the material.
In the case of Glowstone Dust, that item is not "Glowstone" itself. Instead it's actually that Glowstone breaks into dust.
@theqmagnet With Block of Redstone, it makes a lot of sense because it's something that is created by compacting "Redstone" items, rather than itself being the original Redstone.
If we renamed Redstone to Redstone Dust, then it would make sense to change Block of Redstone to just Redstone.
It's kinda wild that so many contraptions in Minecraft are wired up by a bunch of dust. Imagine if real world physics applied and that dust just blew off into the wind.
